OS: Unraid 7.2.3
Docker: Official Jellyfin 10.11.6
Theme: ElagantFin with Featured Content Bar
My overall docker disk space was running low on Unraid and I stopped the docker service to increase the disk size. After I restarted the docker service, I went to finish updating my docker containers and I noticed Jellyfin was not started (it's set to auto start), and Jellyfin did not have an update. I attempted to start the container and I got this message "Server Error".
When I check the logs, the only thing I see are these messages (this is the last lines of the log), pertaining to shutdown the docker container, which is what happens when you stop the docker service in Unraid.

I'm not sure what to check next. I did not make any configuration changes to Jellyfin, I was simply updating my docker containers on Unraid.
I checked the Unraid Log
Feb 4 07:59:45 rc.docker: jellyfin: Error response from daemon: driver failed programming external connectivity on endpoint jellyfin (5f7008baa8c3149e636ad3e62f275a13607d0be80c368478828d0b82c16d0868: failed to bind port 0.0.0.0:1900/udp: Error starting userland proxy: listen udp4 0.0.0.0:1900: bind: address already in use
Feb 4 07:59:45 rc.docker: Error: failed to start containers: jellyfin
So Unraid seems to be saying something is running on port 1900.
When I run Netstat I get this:
netstat -tunlp | grep ":1900"
udp 0 0 0.0.0.0:1900 0.0.0.0:* 3643951/python3
Investigating what service/plugin is using python3 (this has never happened before)
***Update**
So I decided to stop and start the Unraid docker service. Before starting the service again, I also turned off auto start on two new containers I installed since Jellyfin was running, which is Immich and Glances. After starting the docker service Jellyfin container was running and I was able to log in.
When I run netstat on Unraid terminal, port 1900 is not assigned to python3 (still don't know what this is)
netstat -tunlp | grep ":1900"
udp 0 0 0.0.0.0:1900 0.0.0.0:* 3970147/docker-prox
udp6 0 0 :::1900 :::* 3970154/docker-prox
This is resolved.
