Hello Ken,
The model A has a watchdog mechanism: if the network connection drops, it will reboot automatically after 10 minutes. This was added in the newer firmware versions, and your unit has it.
I’d need more details to know what goes wrong with your setup, and a first thing you could test is connecting the unit to a different internet router. Then is changing the power adapter with another one. We’d need this two ruled out before anything else.
L.EDIT: I see it up and running: https://www.uradmonitor.com/?open=110000E7
