The watcher did not receive a test notification (ubuntu client not syncing)

I had a fully functional NextCloud client based on Ubuntu 20 LTS. After upgrading my ubuntu from 20 LTS to 22 LTS using “sudo do-release-upgrade”, I had to reinstall NextCloud (I used the the PPA apt method first ). After reinstalling my folders are not syncing with the server. I get “The watcher did not receive a test notification.” during NextCloud start up. I tryed uninstalling and using the AppImage instead, but got the same result.

Please help
