Can no longer access jellyfin

[prof.mors]

Hello,

Thanks for reading my post,

I have an issue, i was watching something on jellyfin via my roku box and all of a sudden it stopped working, I lost access to my server. i ssh in to my server and i had access. i run a few things from this one server and one of them is jellyfin. 

I checked 3 computers web browsers and none of them can access jellyfin. i ran systemctl status jellyfin and i got this 

× jellyfin.service - Jellyfin Media Server
    Loaded: loaded (/lib/systemd/system/jellyfin.service; enabled; vendor preset: enabled)

i have read a few posts but am not sure what to try first. i did see one post saying check the cache directory in /var/cache and look at the jellyfin folder which i did, the post said the  usern and group on that directory should be jellyfin:jellyfin  mine is jellyfin:adm  could this be the issue? 

I dont want to go around and change things that could make things worse. 

Thank you to anyone reading.

Thanks!

Can you run this command and then share the output saved to the text file to privatebin.net?

Code:

sudo journalctl -u jellyfin -n 500 --no-pager > /tmp/jellyfinLogs.txt

Did your disk fill up recently? It looks like one or more of the XMLs in /etc/jellyfin are empty or corrupt. You can safely delete all the XMLs in that directory. They will be regenerated with default values.
