Sonarr stopped working suddenly

Troubleshooting

Hello,
First post here, sorry if I do not do this correct. Today I noticed that Sonarr just stopped working. Radarr, Jackett and Deluge are working fine. When I go into Dietpi-services and look at the status of Sonarr I get this:

Any help would be appreciated. I have already done dietpi-update and dietpi-software reinstall 144

Hi,

this looks like Mono error messages. You could try to reinstall mono

apt install --reinstall mono-runtime mono-complete
3

No change with Mono reinstall, exact same error.

maybe you can open an issue with Sonarr to check what this issue is about https://github.com/Sonarr/Sonarr/issues

I ended up restoring from Dietpi-backup, manually copying my backed up sonarr configs to a safe place, uninstalling sonarr, installing sonarr, and restoring from back backup configs.

luckily you had a backup. Good it is working now.
