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.

Is this the first time you’ve seen this error? Y

Steps to replicate it:

The system worked correctly. It offered to update one app. It showed an update, but then it went back to the same page and kept offering the update. After refreshing the page, it said that it is in Maintenec mode. I found on the Internet that it is enough to override False in config.php. The system started up again. After restarting the PC, it didn’t start anymore and only writes this error

Output errors in nextcloud.log in /var/www/ or as admin user in top right menu, filtering for errors. Use a pastebin service if necessary.

NO NEXTCLOU LOG

Thank you for all advice
Karel.

ahead of going into things: you seem to have access to commandline. so why not trying disabling and removing problematic app?

like sudo -u www-data php occ app:disable <app> and sudo -u www-data php occ app:remove <app>

3

Not sure which app it was. Is it possible that a failed upgrade of the application can kill the entire nextcloud like this?

The worst thing is that I can’t find any LOG and determine the reason why it doesn’t work

4

I backed up the entire nextcloud directory in www and using a script
https://download.nextcloud.com/server/installer/setup-nextcloud.php

i downloaded the clean version of nextcloud and it works.
i just copied the old config.php file so nextcloud stopped working. Something is wrong either in config.php or there is a problem in connecting to the database that is set in config.php.

For me your setup seems a bit too local. You avoid using proper SSL-certificates and want to run your instance locally only.

Apart from NC needing a proper certificate to run securely ( and flawlessly) i’m afraid it could cause strange problems as well. Plus you won’t be able to share things outside your homenetwork.

Though maybe you need to tell your DB at which port it has to look on localhost. Could be 3306 but I’m not sure

I only use it on the local network. Our mobile phones sync photos to nextcloud and only on our local wifi, so I don’t need SSL. Nextcloud is not accessible from the Internet. MySQL runs on port 3306 - it is his default. I’ll check it today and get back to you

SOLVED :slight_smile:
The problem was in mysql database. It looks like it working, but database was corrupted.
After restore database from backup, nextcloud again works .

Thank you for your time spent on this request

Karel.
