I have my gear set to auto-upgrade so I don't know when the DMP did updates.  The logs have rotated since about 2 hours ago so I can't check the /var/lib/homebridge/homebridge.log for when this started.

I've restarted the child bridge, the rPi the homebridge parent is running on as well as just the Protect app on the Dream Machine Pro.  Finally I shutdown (cold) the DMP, unplugged and plugged back in. Nothing changes the error and, of course, the cameras video/thumbnails do not populate in the Home app.
