Connection Issue with AppleTV

I am not able to connect to my AppleTV. I am able to connect to the Tablo on my computer and IPhone but when I try and connect on the AppleTV nothing happens. I click the Search Again button and I get the wheel symbol and then nothing. It was working fine until 3 days ago. What am I doing wrong?

My Apple TV has worked flawlessly until yesterday. iPad works, Roku works & iPhone. The Apple TV has an error message, Failed to Load. Item not found. Try again.
I’ve rebooted both Tablo and Apple TV. I’ve deleted and reinstalled the Tablo app.

Workaround until the permanent fix is in that thread.
