SOLVED: Error while starting server - unable to connect to server

[.meditate.]

Hi there - any help on the below appreciated, I saw similar requests but nothing seems to have permanently solved the issue for me.

Overnight, without external influence Jellyfin stopped working and I'm unable to connect at all on any device. This happened yesterday too, and I did a total clean install which fixed the issue until last night where I'm now getting what looks like the same errors.

Running on OMV in a docker container through compose, Jellyfin version: 10.10.3

What I've done so far:

• Reboot system
  
• Remove docker container, checked no jellyfin instance running with docker ps
  

Relevant part of the log below - this just repeats over and over after loading the plugins.

Is your disk full? If not, do you have the playback reporting plugin installed?

[.meditate.]

Thanks -- disk isn't full but I do have the playback reporting plugin installed

[TheDreadPirate]

Try removing the playback reporting plugin. It has its own DB that, sometimes, gets corrupted and prevents startup.

/config/plugins/

Remove the playback reporting folder. In /config/plugins/configurations/ delete the XML for playback reporting.

Right -- so I've done as you suggest and rebooted for good measure. But hasn't fixed it although something has changed, I'm getting a new  error for the first time:

Seems like I've solved it for now -- deleted all .xml files in the /config folder and rebooted the container. All seems to work now again!
