Collabora Online Fails to Save Edits

Hello

I’ve been using Collabora Online for real-time document collaboration, but lately, I’ve encountered an issue where documents fail to save intermittently. :innocent:The error message states “Document cannot be saved”, and sometimes, changes made by users are lost after refreshing the page.

This seems to happen more frequently with larger documents or when multiple users are editing simultaneously. :upside_down_face:
I’ve checked the server logs, file permissions, and WOPI integration settings, but nothing obvious stands out. Could this be related to session timeouts, network issues, or conflicts in concurrent editing? :thinking:

Restarting the Collabora service temporarily resolves the issue, but I’d like a more permanent fix.

Has anyone else experienced this? What’s the best way to troubleshoot saving issues in Collabora Online? :thinking: Checked I can create file but cannot save or edit file on collabora RPA UiPath guide related to this and found it quite informative.

Any insights into debugging logs, timeout configurations, or potential server-side fixes would be greatly appreciated!

Thank you !! :slightly_smiling_face:

Hii @Natalie Welcome to collabora online forums

1. Check Collabora Logs

Since you’ve already checked server logs, look specifically for error messages related to saving, WOPI transactions, or timeouts. Try running:

docker logs <collabora-container-id> | grep -i "error\|save\|wopi"

If running natively, check /var/log/coolwsd.log for more details.

2. Verify WOPI Lock Handling

  • Ensure your WOPI host correctly handles lock requests and doesn’t prematurely expire them.
  • Check if any other processes modify the file externally while editing is in progress.

Which Version are you using ?
