I have just setup an Emby server and am able to stream live TV to a browser on the local machine. I can connect to the Emby server from the Fire TV Stick 4k, but when I try to play live TV the screen goes black with the spinning "waiting" timer, no video or audio. Initially I was able to get a few seconds of video and the audio continued after the video froze on the screen, but now I can't get it to stream to the Fire TV at all. Once this happens and I try to "go back", nothing happens and after a short while I end up back at the Fire TV apps screen as if Emby was "Killed" for hanging.
I have forwarded the logs from the Fire TV Stick 4K at 09:32 EST, the logged on user was vance.
Logs from the server are attached.
