At the beginning of every hour the server fails for a few minutes. Symptoms: can not find Tablo and goes to offline mode; if the Tablo is found the guide is blank and does not go to offline mode; if the guide is not blank it gives an error when trying to select any program from the guide to view.
My system is a Roku 4802X and a 2ch 4 gen Tablo connected by Ethernet. My Android phone does the same thing. I am in the Pacific time zone.
