Bug description
For a few weeks now, I have noticed that the Nextcloud Desktop Client no longer automatically synchronizes file changes on the server side. You always have to pause and restart synchronization for it to happen. Or a file has to be changed locally to trigger it and start syncing again.
I have observed this behavior on two Ubuntu computers. On Ubuntu 24.04 and 25.04.
Here are my settings:
Steps to reproduce
- Change a file on the server, either through the webinterface or using another client.
- Resume your PC from suspend and wait.
- Even after an hour the changes were still not synchronized.
- Then change the same file locally.
- A few seconds later the client shows a notification about a file conflict.
Expected behavior
After starting up the PC from suspend the Nextcloud Desktop client should synchronize changed files from the server in the configured 30 seconds interval.

Additional info
The "AppAPI-Bereitstellungs-Daemon" is not configured properly on server side. But I don't think this is the issue.
The same problem occurs with the FreeBSD client. I’m not sure when this regression was introduced, but in the past, at least a forced sync would resolve it. Now even forced syncs don’t help, and new local files are not being uploaded to the server. If I want a newly created file to sync, I have to completely exit the client before creating it and restart it whenever the PC has been hibernated since the client was last launched.
on macos 15.7 sync stalls after wakeup from night deep sleep, E2EE enabled. force sync starts syncing ... again.
