My Nextcloud seems to break every so often for no apparent reason. I’m running it on Ubuntu Server in Docker with MariaDB. Everything is deployed with Ansible. It somehow broke today when I was deploying a completely unrelated service and Ansible logs don’t show any changes related to Nextcloud.
Basically all information I have is the
Internal Server Error page of Nextcloud. None of the log files show any information.
What I tried so far:
- Delete all Nextcloud directories and restart. This “works” but for obvious reasons I’d rather not
- chmod all directories to 777. This does nothing
- Restore the nextcloud directories from an older ZFS snapshot (when it was still running). This also doesn’t work
The DB seems to be up, I can connect to it from the Nextcloud container and if I reset nextcloud it connects normally.
I’m really lost on where to start debugging this. Any pointers would be appreciated
