I have Plex running on a FreeNAS server. The server works just fine on iPads and computers, but I can’t seem to get it to work on my new Xbox One. It is on the same network (wireless) that my iPads use (and they work) same subnet and all of that.
That is what did it. Although it wasn’t as simple as that as I had the server plugged into to a wireless router that was plugged into the internet gateway and it wasn’t setup as a bridge.
Anyway working now. Thanks for the clue to send me in the right direction.
