RPi Connect screen sharing not always availble #170

Closed mehrdadfeller closed 1 month ago

mehrdadfeller commented 2 months ago

Once in a while RPi connect shows screen sharing as unavailable, and remote desktop stops working. I investigated the issue and seems like rpi-connect-wayvnc.service had failed. I guess the service won't attempt to auto-restart if it fails for whatever reason (stopping and starting rpi-connect also did not seem to restart this service.). The issue was fixed after I manually started rpi-connect-wayvnc.service.

I suggest we check for this service status when user presses start on the keypad and also attempt to start/restart this service.
