Jellyfin cannot be accessed on any devices

[slegghetti]

Hello,

After recently updating Jellyfin, I can no longer access the app on any device on the local network (attempted from Windows PC on ethernet, Windows laptop on wifi, iPhone on wifi). I am running 
Jellyfin 10.11.11 on a raspberry pi, and things were working fine last week. I can ssh into the pi just fine, so it has internet access, and the Jellyfin service appears to be running:

Code:

pi@pi:~ $ sudo systemctl status jellyfin
● jellyfin.service - Jellyfin Media Server
    Loaded: loaded (/usr/lib/systemd/system/jellyfin.service; enabled; preset: enabled)
    Drop-In: /etc/systemd/system/jellyfin.service.d

Jul 08 20:11:24 pi systemd[1]: jellyfin.service: Scheduled restart job, restart counter is at 21850.
Jul 08 20:11:24 pi systemd[1]: Started jellyfin.service - Jellyfin Media Server.

The pi appears on my router's interface as well, but I don't have any ports forwarded to set up connectivity outside of my home network. I am also running piHole on the same pi, but these two haven't conflicted in the past, and that seems to be working normally as well and can be access from my browser.

Here is a snippet from a log file created yesterday:

I realize the formatting might make the pasted bash outputs harder to read.  The status of jellyfin can be found here: https://pastebin.com/WJS67KpX

and the log here: https://pastebin.com/KkwZd2xd

Can you go directly to /var/log/jellyfin and share the latest log from there? What you've provided seems incomplete and is not from today.

Sure. Unfortunately both jellyfin20260708.log and jellyfin20260707.log (source of the original log) are 10 MB in size! So I cannot pastebin them. However I have uploaded jellyfin20260708.log to Google Drive which can be accessed here.

There's your problem.

You are correct! Cleaning out /var/backups and /var/log/jellyfin helped, as well as running sudo apt-get autoremove. Thank you!
