So I’ve gone through several of the old posts about this issue, but none of them seem to match my issue.
I run an Apple TV 4K feeding my TV. It’s connected to a gig switch and my provider is synchronous gig fiber. I don’t use a tuner, I am strictly using TVE (via Locast, Directv, Fubo, Xfinity). The issue I have is this. My wife likes to have IonTV play in the background while she works, every 3-4 hours of running without interaction we get the connection lost error. This happens on any one of the 5 TV’s in the house. All with the same set up. Apple TV connected to a gig switch then out to the provider’s gig fiber.
