Today I lost access to my Nextcloud despite no changes to the server in quiet some time. Can someone take a look at the logs and try to help out?

I am seeing this when trying to log in:

Internal Server Error

The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.

I ran the logs before and after rebooting the server. Both attached.

Thanks,

Lev

I was able to roll back a snapshot and got back in to it. However, I am still not sure what happened.

Thank you.
