I've got Plex Home Theater running on a Mac Mini hooked up to my TV. I'm also using the same Mac Mini to run the Plex Server. It's worked fairly reliably over the past few years but I've run into an issue recently that I can't seem to fix.
I control it a lot via the web interface and via HTTP commands but I've noticed that both of these have stopped working. In the web interface I no longer see the PHT player in the cast menu. It's only when I restart the client that it reappears. However after a short period of time (I'm talking minutes) it disappears again.
Any ideas as to why it might be doing this and more importantly, what might fix it?
