Random reboots while watching

Over the last day or so, I have experienced 7-10 random reboots. Occurs while watching live and recordings.
(Added to clarify - broadcast signal drops & Channels restarts).
Further - this is remote viewing (client in NYC, server in PA)

Client: Tivo Stream 4K V9.0-5.4.1
Android Beta: 201.13.245
Server: QNAP TS-253A
Channels DVR Beta: 2022.01.14.2142

Updated: Still occuring
