Summary of the issue you are facing:

I installed the Whiteboard app from the admin interface. I went and created a new Whiteboard from the Files web view. Opened it, edited it a bit. The .whiteboard file remains empty. No changes seems to be stored in there. In the browser, when the whiteboard is open, I can see a red wifi like button red, saying “offline”.

If I close and reopen on the same browser, I can see the contents.

Opening from another browser, the file is empty.

I haven’t installed the websocket server. It is repeated at several parts in the documentation that it’s not required for basic funcionality, only for real-time communication. I only want this feature for my personal notes, I don’t need any collaboration with other users.

Do I still need some sort of external backend or server?

Steps to replicate it (hint: details matter!):

  1. Install whiteboard app (only)

  2. Create whiteboard file

  3. Edit, close

  4. Open from other browser

  5. Whiteboard is empty

  6. Open again from first browser

  7. Whiteboard content is there

Tips for increasing the likelihood of a response

  • Use the preformatted text formatting option in the editor for all log entries and configuration output.
  • If screenshots are useful, feel free to include them.
    • If possible, also include key error output in text form so it can be searched for.
  • Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
