SOLVED: Accessing the web server

[TheDreadPirate]

The UFW rule is what I'm looking for. Jellyfin does not open the host firewall automatically on Linux (it does on Windows during install). The "Automatic port mapping" is for creating a uPnP rule on your router. Which would be used for remote access.

What is the output of "sudo ufw status verbose"? Did you set any additional UFW restrictions? Like default deny on outgoing traffic? I'm assuming no based on your current rules, but I have to ask.

I also don't know what your network topology is like. Sounds like it is more complex than a typical user's "flat" (single VLAN) network. Are your server and clients on the same VLAN?
