## Common questions

### Did previous TrueNAS SCALE deployments of ONLYOFFICE Document Server require a JWT secret?

A reply in the TrueNAS SCALE thread says a previous setup needed to set the JWT secret.

### What should documentServerUrl point to when configuring an ONLYOFFICE editor?

It should be the full base address of your ONLYOFFICE Document Server, and the document URL in the config must be reachable. If the server address is wrong, the editor cannot load DocsAPI and will fail with an error.

### Why can edits be lost if I stop ONLYOFFICE Docs while editors are still connected?

ONLYOFFICE Docs saves a document only after the document has been closed by all the users who edited it. To avoid data loss, you must forcefully disconnect the ONLYOFFICE Docs users when stopping the application for an update.

### What third-party sync and share solutions can be used with ONLYOFFICE Docs?

ONLYOFFICE Docs can be used with third-party sync and share solutions such as Odoo, Moodle, ownCloud, and Seafile.
