SOLVED: Jellyfin App on Amazon Fire TV 4K issues

[TheDreadPirate]

Is the FireTV on the same network as the server? Are you using a reverse proxy? Do all clients, remote AND local, go through the reverse proxy? Assuming you are using one.

I see this message a lot, which tells me there is some weirdness with your network or some network related config.

Code:

error receiving data: The remote party closed the WebSocket connection without completing the close handshake.
