Nextcloud 500 error - where to start searching

[kdeiss]

I'm using the team container for several month now without any problem. Installed as vm-guest under esxi.
Last week we had a power failure. After reboot nextcloud isn't working anymore.

The instance seems to run:

kubectl get pods
NAME READY STATUS RESTARTS AGE
svclb-traefik-6zjzv 2/2 Running 42 263d
traefik-694bfcf5fd-s6phg 1/1 Running 21 263d
landingpage-7d68966c84-5rf8f 1/1 Running 21 263d

nextcloud-team-nextcloud-nc-54b875ddd5-kgn7s 2/2 Running 43 263d

But if I want to access nextcloud with browser I receive

Unfortunately I'm the administrator but I have no idea.......

I found entries like this:

Where can I start searching for this error?

thanks in advance!

Hi there,

I am sorry for leaving you alone for months with this project. Now I am back to game and will look for a solution. I think there are some changes by the Nextcloud team. I will investigate what's going on.

there is a workaround for this error here, in my case patching of RedisFactory.php is working but needs to be done after every restart: https://www.heise.de/forum/c-t/Kommentare-zu-c-t-Artikeln/Dateiablage-Videokonferenz-und-Chat-auf-dem-eigenen-Server-betreiben/Re-Nextcloud-meldet-internen-Serverfehler-nach-dist-upgrade-unter-Ubuntu18-04-2/posting-38066471/show/

Hallo,
In the meantime there is a persistant solution, it can be found here:

This is more easy and a persistant solution, it will survive a restart of your server.
