### Additional context
I had also been getting a previous error about not being able to reach ring server, but I fixed this by changing my router's DNS settings away from my ISP's (to CloudFlare). Things seemed to settle down, but now I am seeing these errors (which I saw as being fixed by a previous release). The cameras are stick-up cams wired to the mains.
