Apple TV Tablo Failure

After months of perfect performance, my Apple TV Tablo app failed during the PAC 12 championship game tonight. The app finds my Tablo on the network but will not connect. All I get is "network error ". All other Apple TB apps are working fine. My Roku Tablo app is working fine. I’ve reset the Tablo and modem/router, deleted and re-loaded the app twice, no joy. Any ideas?

After 12 hours of rest, everything seems back to normal.

Same thing happened to my Apple TV 4. Got the same error message and then an hour or so later it was back to normal.
