Your private workspace, on your hardware.

What is OneStop?

OneStop is a self-hosted workspace for files, photos, documents, spreadsheets, music, video, calendar, tasks, contacts and email. This guide is reviewed against server 2.1.119 and its release notes. Guide reviewed October 18, 2026. Android apps are distributed separately. Check each app’s Google Play listing for its current availability; the server installer does not publish or update phone apps. Your server stores the workspace; browsers and paired clients connect to it.

The server installer and Desktop Sync are different applications. Install the server on the computer that will host your library. Install the appropriate Desktop Sync client on a computer that needs a synchronized folder. Windows packages include Windows Sync; the Ubuntu package includes Windows Sync and Linux Sync preview.

This page offers both the Windows server installer and the Ubuntu server. Choose the package for the server computer. Ubuntu Server 24.04 x64 has passed the VM release checks. Linux Desktop Sync remains a preview; see the Ubuntu guide for the exact tested scope and remaining recovery/network limitations. The Windows EXE does not install an Ubuntu server.

What’s new in OneStop Server 2.1.128

Mail navigation and phone menu improvements, connected calendar sync, and optional Google Tasks import into editable OneStop copies.

• Mail 3.0.65 reuses bounded sanitized message markup in memory, reducing repeated work when opening saved messages. Phone action menus stay within the screen, and Older messages is a compact control. Reading speed for uncached messages and images still depends on the server and network.
• Tasks 3.0.21 adds Import Google tasks: choose tasks to copy into editable OneStop tasks. Repeated imports and reconnecting the same Google identity do not duplicate copies or overwrite local edits. Google originals are unchanged; imports are optional and require a separate Google Tasks read-only connection. Server 2.1.128 or later is required for editable imports.
• Mail 3.0.65 removes its forced one-second native splash delay. An unlocked device can show its encrypted saved inbox while the server validates the saved sign-in. Up to 300 full messages fit within an 8 MiB Android body cache; web copies stay in memory. First use and uncached messages still need the server.
• Mail checks on opening and every 150 seconds while active, with manual refresh available. Closing a message does not start another mail check. A small Checking for new mail popup lasts at most three seconds and never blocks reading; slower work continues separately.
• Reading a message no longer starts a full mailbox import for formatting repair. The isolated HTML renderer reports its first layout immediately, and background prefetch is separated from foreground Android requests. A transient broken connection may be retried once for a safe read; writes are never replayed automatically.
• Calendar 3.0.31 adds pull-down sync. Its Sync button now refreshes connected providers and Google Tasks, then reloads the saved view. An unavailable provider no longer prevents local events and tasks from displaying. Android can restore encrypted saved calendar data.
• Google Tasks is a separate, optional read-only Google account connection. Authorized tasks, task lists, completed states and due dates appear in OneStop Tasks 3.0.21; dated tasks also appear in Calendar. Grant Google Tasks access once through Connected calendars or Google Tasks settings. Connected Google tasks stay read-only unless you explicitly import editable copies into OneStop. Later Google changes do not overwrite imported copies. A Calendar subscription or mailbox password alone does not grant Tasks access.
• Google and Microsoft event connections, HTTPS CalDAV and read-only ICS feeds remain supported. Individual providers retain their configured automatic schedules; an app refresh can request an immediate sync. Today and the selected day keep distinct calendar highlights.
• Music 3.1.21 includes the preceding streaming timeout, startup recovery and low-to-high bandwidth selection fixes, plus screenshot support. It was confirmed in Google Play review on October 28, 2026. Availability depends on Google approval and device update; buffering-free playback and physical Android Auto results are not claimed.
• Photos 3.0.73 retains the camera capture speed, JPEG size and supported-device exposure improvements, background transcription, and screenshot preference. Actual camera quality and file size depend on the device and scene. Video 3.1.29 retains subtitle and playback diagnostics improvements.
• Other prepared Android companions are Contacts 3.0.22, Documents 3.0.18, Files 3.0.17 and Spreadsheets 3.0.16. Phone apps are distributed separately; server installers do not publish or automatically replace installed apps.
• Windows and Ubuntu are alternative server installations. Ubuntu targets Ubuntu Server 24.04 LTS x64; Linux Desktop Sync remains a preview. The Windows server installer is unsigned. Back up existing installations before updating. Exact package and upgrade checks are recorded with this release.
• Roku Video remains in development and testing, outside the Streaming Store. Review submission and publication remain on the owner hold. This website updater does not publish phone or Roku apps, send newsletters by default, change prices, enroll payouts or change subscriptions.

OneStop Video for Roku is still in development and testing, and is not yet available in the Roku Streaming Store. Public release depends on further testing and approval. Ubuntu Server is released for Ubuntu 24.04 x64; Linux Desktop Sync remains a preview. Features require the appropriate server and app updates; these server downloads do not update installed devices or publish apps to a store.

Back up your server before upgrading. Read the full October update and platform notes.

Install and create the administrator

Start with the Windows installation guide or Ubuntu installation guide. The Windows walkthrough below does not apply to Ubuntu.

1. Use Windows 11 or Windows Server 2022 or later, x64. Download OneStop-Setup-2.1.128-x64.exe (the website may name the download OneStop-Setup.exe), verify its published checksum, and run it as administrator. Keep a backup before upgrading; do not uninstall to apply an update.
2. Read the displayed license and terms of use. If you agree, select I accept the agreement (version 2026-10-12.1) to continue. The checkbox starts unchecked.
3. Choose local-only access, internal HTTPS, or public HTTPS. A new public server needs its own hostname, DNS and reachable HTTPS endpoint. Reusing another server’s hostname does not move that server or its data. Internal HTTPS requires trusting the installation’s local certificate authority on each connecting device.
4. Choose a dedicated storage folder outside Program Files. Keep its disk connected. Upgrades preserve the saved storage and network settings.
5. After successful setup, open OneStop at the configured address. As Windows administrator, read C:\ProgramData\OneStop\setup-code.txt (or the selected data directory). Use that one-time installation setup code to create the first administrator account. On an existing installation, sign in with your existing account instead.
6. Only the administrator creates additional accounts. There is no public account-registration flow. Existing users sign in with their assigned credentials or registered passkeys.

Register additional passkeys from your signed-in account’s security settings. Device biometrics or Windows Hello authorize a passkey on that device; they are not a public “Create Account” method.

Upgrade and repair

Back up first, then run the cumulative 2.1.119 installer over the existing installation and review the agreement. Setup stops the OneStop services during the upgrade, so plan for a brief interruption. Keep your existing data folder and configuration. After setup, sign in, confirm Version: 2.1.119 in Support information, and check Settings → File protection.

This release includes the scanner-port selection and startup-readiness fixes. If another application occupies port 3310, setup can save an available alternative. Do not stop unrelated applications or disable scanning to complete installation.

Unattended installation and terms

Administrators who have reviewed and accepted the agreement must include /ACCEPTTERMS=2026-09-23.1 when using silent Windows setup. An older acceptance version is rejected. This switch only records agreement acceptance; it does not replace network, storage or other deployment configuration.

Successful setup records the accepted terms version, hash and time locally. The receipt is not automatically sent to Greenlyz and is not tamper-proof. Open Help & FAQs → OneStop license & terms of use to read the installed terms, or select Download terms to keep a copy.

Ten apps, one OneStop workspace

Connect each Android app to your own OneStop HTTPS server. An account on that server is required. The Android apps are still in Google Play review. App-store download links will be added after approval; the server downloads do not install phone apps. iPhone native distribution is not available in this release.

Screenshots in this guide were captured September 23 in a sample web workspace. Documents, Spreadsheets and Files feature graphics are illustrations, not screenshots. The images are references, not proof of current store availability.

Official OneStop app icons are shown below. These are app artwork, not screenshots. Android store links will appear after approval.

Navigation and storage

Use the navigation icons to open each workspace. The storage bar shows your account’s used space, limit and remaining capacity. Account quota is different from the physical free space on the server disk.

Settings uses a left sidebar: select a category to see its controls on the right. Choose light or dark appearance and optional banner or background images under Appearance.

OneStop Photos

Capture, find and organize your memories.

What you can do

• Native photo and video capture; front/rear cameras; tap to refocus and focus feedback.
• Recent-capture thumbnail, photo viewing with pinch/pan and double-tap zoom.
• Albums, favorites, editing, optional memories and local face grouping.
• Local subject/text search and photo-analysis tools on the server.
• QR detection with a tappable result; camera backup subject to phone permissions.
• Portrait background blur and enhanced night capture on cameras that expose these features.

Get started

1. Connect the Photos app to your HTTPS OneStop server and sign in.
2. Grant camera and media permissions for the features you use. Capture a photo or open Library.
3. Name and correct suggested people in Photos; enable optional analysis in server settings.
4. Choose Portrait in camera options when available. In focus clears after one second.

Portrait is automatic subject/background separation, not a tap-to-select blur mask. Camera capabilities vary. Recognition is approximate and is not identity verification.

OneStop Documents

Write, format and work together.

What you can do

• Rich text, headings, font controls, colors, lists, alignment, links and tables.
• Paragraph line spacing, page setup, paper size, orientation and margins.
• Collaborative editing and autosave with saved status.
• Templates, browser spell check, print/PDF preview and HTML copies.
• Supported uploaded document editing through Files.

Get started

1. Create a document or choose a template.
2. Format using the toolbar; use Page setup for paper and margins.
3. Wait for Saved before closing; share supported edit access for collaboration.
4. Use Print / PDF and match paper, margins and print scale.

HTML download is not a Word export. Complex Office formatting may not round-trip exactly. Browser and printer settings can change pagination.

OneStop Spreadsheets

Plan, calculate and organize.

What you can do

• Multiple worksheet tabs and cross-sheet references.
• Supported formulas, cell ranges and formula help.
• Fonts, colors, alignment, wrapping and number formats.
• Templates, collaborative editing and autosave.
• Print/PDF preview and workbook data download; separate uploaded XLSX editing.

Get started

1. Create a workbook and add sheets with Add sheet.
2. Enter values or formulas; use Formula help for supported functions.
3. Select ranges to apply formatting; use sheet names in cross-sheet formulas.
4. Print / PDF or download the collaborative workbook as JSON.

This is not full Excel compatibility. JSON download is not XLSX export. Uploaded XLSX files use a separate editing workflow.

OneStop Files

Your folders, available across devices.

What you can do

• Upload files or folders, including drag-and-drop folder hierarchy.
• Browse, move, copy, download and send items to Trash.
• Supported previews for text, pictures, PDF, audio and video.
• Supported TXT, DOCX and XLSX editing.
• Resumable transfers, storage quotas and protected upload scanning.
• Windows Desktop Sync with two-way synchronization and conflict copies; Linux Desktop Sync preview is included with the Ubuntu server bundle.

Get started

1. Create folders, then upload or drag in your files.
2. Open supported files to preview or edit.
3. For Windows sync, download Desktop Sync from Settings → Desktop & phones.
4. Generate a pairing code, enter the HTTPS server address and choose a dedicated local folder.

Protected uploads support at most 2,047 MiB per file; quotas and available disk space still apply. Scanning large files can take several minutes. Synchronization can propagate deletions and is not a backup.

OneStop Calendar

Bring your schedules into one view.

What you can do

• View local, shared and connected calendar events in Day, Week, Month or Agenda. Today keeps its blue marker while another selected date has a pale blue marker.
• Calendar 3.0.31 supports pull-down sync. Its Sync button requests current data from connected providers, then reloads events and tasks. Local and saved items remain available when one provider fails.
• Connect Google or Microsoft calendars, HTTPS CalDAV calendars or read-only ICS subscriptions. Keep separate colors, visibility and automatic schedules. Supported event edits include conflict checks.
• Dated OneStop tasks appear alongside events. A separate optional read-only Google Tasks connection adds the tasks you see in Google Calendar; Calendar or mailbox access alone does not grant Tasks access.
• Android can restore encrypted saved calendar data. Connect provider accounts once in the browser; server-owner OAuth setup and the appropriate Google APIs are required.

Get started

1. Use + to create a local event, or open Connected calendars to add a source.
2. Choose the source’s calendars, color, visibility and refresh interval.
3. Use My calendars to create a subscription link. Choose busy-only or the offered event details.
4. Enable phone reminders, then adjust notification and reminder settings as needed.

Google/Microsoft connections require server-owner OAuth setup. ICS subscriptions are read-only. Shared feeds exclude imported/shared external events, and recipients control refresh timing. Provider behavior and notification timing vary; universal calendar compatibility is not claimed.

Current calendar behavior

Desktop Month view includes upcoming items; the phone view combines event dots with an agenda. Selecting another date preserves your chosen Day, Week, Month or Agenda view. Open event details before editing. Shared events respect view/edit permissions; owner-only actions remain restricted.

Invitation details show readable organizer names, with original addresses under Technical details. Older events can recover missing participants from saved original invitation metadata or attachments. Existing title, notes and time edits are preserved; no participant details can be recovered if the original data is unavailable.

OneStop Tasks

Turn plans into clear next steps.

What you can do

• Create private OneStop tasks with priorities, due dates, numbered notes and completion states. Dated tasks also appear in Calendar.
• Tasks 3.0.21 shows connected Google task lists, due dates and completed states through a separate optional read-only Google Tasks authorization.
• Open Google Tasks settings in Tasks or Connected calendars, grant access once in the browser, and use Sync to refresh. The server also checks connected task accounts automatically.
• Choose Import Google tasks to copy selected tasks into editable OneStop tasks. Copies keep due dates and completion state; Google originals stay unchanged. Repeat imports skip existing copies, and later Google changes do not overwrite your OneStop edits.
• Provider tokens and cached task data are encrypted on the customer server and scoped to the OneStop account.

Get started

1. Open Tasks and create a task.
2. Set the due date and priority where needed.
3. Use numbered entries and Add item or Enter to extend the list.
4. Mark the task complete when finished.

Adding an email or contact does not automatically send an assignment. Task data stays in the OneStop workspace.

OneStop Contacts

Keep people and business details together.

What you can do

• Contact cards with names, company, job title, addresses, phone numbers, email, website and notes.
• Contact pictures and business-card images.
• Business-card camera capture with front and optional back; server-side text recognition and review.
• Connected Google contacts and Outlook’s main Contacts folder.
• Source labels, scheduled refresh and edits to supported connected-contact fields.

Get started

1. Create a contact manually or use the business-card camera.
2. Capture the front and optionally the back, then review extracted fields before saving.
3. Use Connected accounts for supported Google or Microsoft contacts.
4. Edit supported fields on the correct source contact; use stored addresses in Mail where offered.

New contacts and business-card scans save to the local OneStop address book. Connected contact creation/deletion, structured address edits and Outlook subfolder selection are not exposed. Accounts are not automatically merged.

Connected photos and planning

Google and Microsoft contact connections can supply contact photos. Uploaded pictures take priority; matching local contacts can use provider pictures when primary email addresses match. Missing pictures fall back to initials. Mail credentials alone do not grant contact access.

Use Schedule or Add task on a contact to open its form. Review the carried-over name, email and phone details before saving. Creating an event or task does not itself send an invitation or assignment.

OneStop Mail

A clearer place for your connected email.

What you can do

• Read, compose, reply, forward, search and manage folders, stars, pins and attachments from an existing IMAP/SMTP mailbox.
• Android Mail 3.0.65 restores an encrypted saved inbox after device unlock while the server validates the saved sign-in. Up to 300 full messages fit within an 8 MiB body cache; first use, uncached messages and remote images need a connection. Web mail uses a memory cache.
• The active app checks on opening and every 150 seconds. Closing a message does not start a check. Pull down or use Sync for an immediate check. A nonblocking checking-for-mail popup lasts at most three seconds; slower checks continue separately.
• HTML messages fit the reader and report their first full layout immediately. Bounded in-memory markup reuse reduces repeated rendering work when opening saved emails. Phone menus stay inside the screen. Image and link preferences are remembered; the toolbar remains accessible while the subject, sender and body scroll.
• Tap a sender picture to open a matching OneStop contact or create one. Custom sender pictures remain on the customer server.
• Invitation cards support Add to calendar and Accept & reply through the connected mailbox. Optional Android notifications follow device scheduling.

Get started

1. Open Mail settings and enter your provider’s IMAP/SMTP details and app password if needed.
2. Open a message. Use HTML or Plain text and Show/Hide images to set your display preference.
3. Expand the sender line or Message security only when needed.
4. Choose Add to calendar for a local event copy, or Accept & reply to send an RSVP through your configured mailbox.

The running server listens for provider notifications and performs routine checks every 150 seconds while idle. Failed imports retry after five seconds; busy imports receive a follow-up check. Newest messages import first and storage quota still applies. This is not a guarantee of immediate delivery. Android background alerts use scheduled polling and may be delayed. OneStop is a mail client, not public email hosting. Folder actions manage the OneStop copy. Windows Mail requires a connection. Android Mail can restore its encrypted saved messages; web copies remain in memory. Email links are enabled by default in current Mail; a saved choice to disable them is respected. Change Open email links in browser in Mail settings. Message-security address details remain text-only.

Inbox, selection and message display

Mail offers sender avatars, folder tabs, search, unread/starred filters and compact display. Desktop uses a split inbox/reader; phones provide a Compose button. Long-press a message to reveal selection controls, then select messages or the whole folder for supported bulk moves. Cancel selection or Android Back leaves selection mode. Swipe actions are configurable.

Folder counts and Load older messages expose messages already stored in OneStop. Open email formatting fits automatically; attachments are collapsible. Older formatting is repaired when the provider original remains available. Reload original formatting is optional troubleshooting, not a required step. Image controls apply to ordinary and supported background pictures; sender scripts and active forms remain blocked.

The open interface refreshes saved mailbox changes; returning to the foreground or reconnecting refreshes again. Mail 3.0.42 supplies the matching Android client changes, but its Google Play release is still under review. Background Android scheduling can delay alerts even while the server continues checking mail.

OneStop Music

Your library, at home and on the road.

What you can do

• Browse your customer-owned music library by song, album, artist, playlist or favorites. Use Now Playing and Up Next, shuffle, repeat and sound presets.
• Android Music and Android Auto share the native playback service. Download songs, albums or playlists before travel for offline listening.
• Music 3.1.21 includes streaming startup, timeout-recovery and low-to-high bandwidth selection improvements plus screenshot support. It was confirmed in Google Play review on October 28, 2026; check Google Play for current availability.
• Adaptive streaming can lower bitrate after connection trouble and raise quality after recovery. It cannot guarantee playback without buffering on every network or device.
• Automatic album-cover lookup is an optional saved setting. Existing covers and explicit artwork choices remain available.

Get started

1. Upload music from your phone or add it through your desktop sync folder.
2. Choose a song, album or playlist; use Mix for your whole library.
3. Choose shuffle or ordered playback, and enable repeat to keep playing.
4. Download before travelling and let downloads finish while Music is open.
5. For missing artwork, use Find album & cover and select the correct release.

Automatic phone-folder sync is not included. Downloads are removed on sign-out. Online cover lookup sends identifying music text, not audio. Android Auto availability depends on installation and vehicle support; physical vehicle qualification is still pending.

OneStop Video

A personal screening room for your library.

What you can do

• Home, Movies, Shows, My list and Personal library views with search and sorting.
• Covers, descriptions, favorites, watched status, red progress bars and Continue watching.
• TV series grouped by show and season with episode navigation.
• Native Android playback with standard icons, seek, resume, speed and controls that hide during playback.
• Automatic title matching after upload or every 15/30/60/90 minutes or daily; cached provider results.
• Custom artwork and details; rename My list; app-local light/dark appearance; supported browser casting.

Get started

1. Upload videos to your server or add them through Desktop Sync.
2. In Video settings, configure Covers & title matching and choose a scan schedule.
3. Use TVmaze for supported TV matching without an account; configure TMDB or TVDB credentials when using those providers.
4. Review uncertain matches, or supply your own title, cover and description.
5. Tap a title to play; tap the player to reveal controls.

Matching depends on filenames, metadata and provider coverage. There is one renameable My list, not multiple custom video lists. Offline video downloads, subtitle selection and native Android Cast are not included. Browser casting requires a supported setup.

OneStop Video for Roku — in testing

The Roku video app is not yet available in the Roku app library. We plan to release it after testing and Roku approval; no date is confirmed. Server 2.1.119 includes support for the pairing, playback and watch-progress features currently being tested. This is not a public Roku download and is not installed by either server package.

Faces and people

Optional face grouping processes photos on the OneStop server. Review suggested groups and labels; detection can miss or misidentify people. Photo face grouping is separate from passkey sign-in and is not identity verification.

Notifications and phone apps

Enable new-mail alerts or calendar reminders in the relevant Android app, then allow Android notification permission. Initial setup can be dismissed; later changes are available in app settings and Android notification-channel settings.

Mail background polling is scheduled approximately every 15 minutes and can be deferred by Android. Calendar caches upcoming reminders; optional precise-alarm access improves timing. Do Not Disturb, battery restrictions and connectivity affect delivery. These are not guaranteed instant push alerts.

Camera backup also follows phone permissions and background scheduling. Check that files have reached the server before relying on backup. Desktop Sync 2.1.7 and Windows Mail 1.0.2 are available through your server’s Settings. Windows Mail includes Calendar and Contacts navigation and uses the updated server interface.

Settings and sharing

Select categories in the left sidebar for appearance, sign-in/security, accounts, storage, desktop/phones, photo preferences, imports, backup/access, file protection and security activity. Protected changes require a recent password or passkey verification.

On Sharing, select an item and permission, set an expiry and optionally restrict the recipient or add a password. Copy the created link and revoke it when no longer needed. A link without recipient/password restrictions can be used by anyone who possesses it until it expires or is revoked. Edit permission enables supported collaborative editing.

The tip jar directs voluntary tips to Greenlyz, with a $5 USD minimum. Payment processing is handled through the Greenlyz/Stripe flow; a tip does not buy storage or unlock features. Ordinary OneStop installations do not need Greenlyz’s Stripe secret key.

Accounts, quotas and backups

Only administrators create accounts and adjust account quotas, including their own. Decreasing a quota does not delete existing files; additional storage-consuming operations may be blocked while the account is over its limit. Increasing a quota does not create physical disk capacity.

Backup & remote access provides instructions, installed administrator-tool commands, a server address and a connection test. It does not create a VPN, open your router, or automatically schedule a backup. Its connection test does not prove outside-network reachability.

Use the backup/restore tools for your server platform. On Windows, run the installed PowerShell tools as administrator. For Ubuntu, follow the bundled backup.sh instructions and Ubuntu backup guidance; do not run Windows recovery scripts on Linux. Full-server backup pauses services for consistency. Keep the encrypted library and recovery key in protected storage outside this computer, and test restoration before relying on it. Never paste setup codes, passwords or recovery keys into support messages.

Recover a lost administrator password

Use a saved recovery code first if available. If all recovery methods are lost, Windows releases since 2.1.51 include a local recovery tool. The following steps apply only to Windows. For Ubuntu, contact your server administrator and use its platform-specific recovery procedure. It resets an existing OneStop administrator; it does not create an account or grant administrator privileges.

1. On the computer hosting your OneStop server, sign into Windows with administrator rights and open PowerShell as administrator. Take a normal encrypted backup first when possible.
2. Run the installed tool (adjust the application path if necessary):

   powershell.exe -NoProfile -ExecutionPolicy Bypass -File "C:\Program Files\OneStop\tools\Reset-OneStopAdministrator.ps1"

3. Check the displayed data folder, enter the existing administrator username, confirm the operation, and enter a new 15–128 character password twice. Password entry is hidden. Follow ADMINISTRATOR-RECOVERY.md in the installation folder for nondefault paths and full instructions.
4. Sign in with the new password. Register fresh passkeys, generate and safely store new recovery codes, and re-pair devices.

This revokes that administrator's old sessions, passkeys, recovery codes and device pairings. OneStop and its proxy stop briefly and restart if previously running. Files, encryption keys and other accounts are preserved. A database recovery copy is saved before the change; protect it because it contains old authentication records. It is not a full backup of your files and encryption keys. Do not replace the live database with it or delete the encryption key.

Installing a server update does not itself reset any password. There is no public website recovery endpoint. If you lack Windows administrator access, contact whoever controls your OneStop server. Publishing this installer on Greenlyz does not run the recovery tool.

Security and privacy

Remote access requires HTTPS. Stored file and mail contents are encrypted with server-managed keys: this is not end-to-end encryption, and an administrator with access to the server’s keys can decrypt them. Password/passkey policy, sessions, sharing restrictions and device revocation govern access.

The local scanner checks uploads, sync completion, file access and email attachments. A detected threat or failed inspection blocks the protected operation. The scan limit is 2,047 MiB per file (2,146,435,072 bytes); unsafe encrypted archives, exceeded scan limits and unavailable or stale protection can block access.

Check protection status reports scanner health with a green check or a red failure explanation. It is not a scan of the entire library and cannot guarantee that every threat will be detected. Keep the server operating system, scanner definitions and OneStop updated.

An unsigned-publisher prompt is different from a malware detection. If Defender reports a threat, leave the file quarantined, retain detection details and contact support. Do not disable protection or add an exclusion to install OneStop.

See the OneStop privacy notice for data handling and operator responsibilities.

Help, FAQs and support information

1. Open Help & FAQs from OneStop’s navigation, Settings or sign-in page. It is also available at /help on your own OneStop server.
2. Use Search common questions to search for a topic such as setup, printing, sync or security. Expand a question to read its answer.
3. When signed in, select Copy support information. The report includes the running server version, operating-system platform, architecture, Node.js runtime, original installation date when recorded, last successful setup/update date and recorded installer version. Older dates may be shown as not recorded; this does not mean your data is missing.
4. Select Submit a help request to open Greenlyz Helpdesk. Paste the report and describe what happened, when it happened, the steps to reproduce it and the relevant error. If clipboard access is unavailable, select and copy the report manually.

The support report excludes account names, server addresses, file paths, credentials and documents. Opening Helpdesk does not attach logs or private files automatically. Review any extra information before sending it; never send passwords, setup codes, recovery keys, API keys or session tokens.

Your local OneStop administrator remains responsible for creating accounts and resetting access. Greenlyz Helpdesk does not automatically have access to your private server or its accounts.

Troubleshooting

Service setup failed

Do not delete the data folder. Read C:\Program Files\OneStop\install-service.log and the logs in your OneStop data directory. The installer’s runtime line number is not the underlying error. The Windows 2.1.119 installer retains the scanner-startup retry repair for Windows PowerShell 5.1; no separate repair script is required. For Ubuntu service errors use the Ubuntu guide, not these Windows paths.

Port 3310 is already in use

For Windows, use the current cumulative installer. It includes the earlier fix that prefers the saved scanner port and selects an available alternative in 3310–3399 when necessary. Do not kill an unrelated process, expose the scanner port to the internet or point OneStop at an unknown scanner. The selected port is written to config.json as malwarePort.

File protection is not ready

Check protection\clamd.log, protection\freshclam.log and protection\readiness.log in the data directory. Confirm available memory, current scanner definitions and the status of the OneStopAntivirus and OneStopDefinitions services. A red status can mean scanner unavailability, not necessarily an infected file. File access remains blocked while required scanning is unavailable; do not disable protection to clear the warning.

Silent setup refuses to continue

Check that your deployment command explicitly accepts the current agreement with /ACCEPTTERMS=2026-10-12.1, after you have reviewed it. An older terms version does not satisfy this installer. In interactive setup, read the agreement and select its acceptance checkbox if you agree.

Support information shows older or missing dates

Installation dates from older installers may be unavailable. Compare the running Version with the Installer version and last successful setup/update date. If the running version is still old after upgrading, retain the installation logs and submit a help request rather than repeatedly reinstalling or deleting data.

HTTPS or sign-in fails on another computer

Confirm the correct server address, DNS, certificates and network reachability. Register passkeys against the permanent address. A second server cannot take over an existing hostname merely by entering it during setup. Existing users sign in; contact the administrator for account recovery.

Mail or imports stop

Review the displayed error, provider connection and credentials, available quota and server disk space. Keep original exports until you verify the imported library. Do not repeatedly start duplicate imports to clear an error.

For product support, use Greenlyz Helpdesk and include your support information. Remove secrets and private document contents from any logs before sharing them.
