RockyLinux 9 docker- No network

[sam512]

This may be a Rocky Linux question, but my issue is specifically with the Docker install. I did a Google search and first came up with guide at Howtoforge. Seemed simple enough, just copied and pasted a few lines. Docker image starts. Problem though while port 8096 is specified in the Docker compose config, on the host doing netstat -tulpn shows nothing. So I tried playing around some with little to no knowledge of Docker. I tried to do a Docker pull of a different image 'lscr.io/linuxserver/jellyfin', even added commands to change network from bridge to host.

Closest I can come to is at one point I did see port 8096 showing up on the host used by jellyfin, but could not access from another PC's browser. I did stop the firewall, did set SELinux to permissive. Ironically part of the reason I am most ignorant with Docker networking is that images in the past I have looked at always just worked.

I am having trouble thinking this is a problem with the Jellyfin container and more something with Rocky that I am unaware of. I did try to do an install from RPMfusion, that just threw up dependency errors starting with FFPEG.  I do get this in log:

Anyone experienced with Jellyfin on RockyLinux, or familiar with similar issue?

Edit: For reasons too long to explain I decided to install Oracle Linux 8, Docker, and then Jellyfin. Very first time I started the image I did see port 8096 being used by Jellyfin using netstat. A few moments later it disappeared. I looked at message logs and saw same errors.  This is strange because I had a VM running Oracle 8 with docker and a few containers running. Shame because I just deleted that VM back in October and never got around to making a new one. However on this Oracle 8 installation I was able to install by downloading rpms seperately for Jeyllyfin, FFMPEG, and misc packages required and it is now running. In theory I would prefer the Docker container but could use this if needed. So problem solved? 50% Yes and 50% No.

Is SELinux enabled?
