Apple TV app "unable to play"

Apple TV app quit playing a show and now when I try to watch anything on Apple TV app I receive the message "unable to play". When I select "start troubleshooting" it says "unable to connect". My WiFi is working fine. Any other app on my TV, phone, or computer works just fine. I've tried the AppleTV app on my phone and computer to check, and I'm unable to play videos on any of my devises.
