Apple TV

So I have used Apple TV in the past with my Xfinity service and had no issues. But now I'm having issues for some reason, I was attempting to check to make sure everything was authenticated and I received a message saying that I don't get a channel because it isn't a part of my Comcast TV subscription... But I was just watching it on my regular TV. Anybody help me out here? It's the watchESPN app.

 

Thanks!!!!
