Tablo not comin up on TV

Hisense Roku TV. Dual Tablo four years old. Was working until today.

Is the Roku app just not finding your Tablo? Can your other apps find your Tablo?

I recommend rebooting your Tablo first to see if it fixes the issue. If not, try rebooting your router. Sometimes the router loses track of Tablo clients, and a reboot helps find them again.

The problem suddenly cleared.
It may have been an Xfinity internet issue with Hisense Roku TV.
