Tablo Quad non HDMI

I am using the Quad non HDMI. I can no longer access my tablo. When I click on the APP, it cannot find my Tablo. Haven’t changed any settings. Using it wirelessly since day one. Any ideas on how to get my Tablo up and running.

My Dual 64 did the exact same thing two days ago after working for years. Unplugging did nothing. I had to hold the blue reset button and factory reset and set up as new. After that it works again.
