SOLVED: All client connections are black screen

Can you configure Jellyfin to only bind to your LAN IP? If you can't get to the UI to make that change, you can manually edit network.xml.

Replace this

Code:

<LocalNetworkAddresses />

With this

Code:

<LocalNetworkAddresses>
    <string>"192.168.12.34"</string>
  </LocalNetworkAddresses>

I'm assuming that 192 address if your actual LAN IP.

After making that change, restart Jellyfin.
