Oddly, I solved the problem. I assume most of you are also using Google
wifi pucks of some type (I am using Nest WifiPro with wired ethernet
backhaul to all pucks). Simply restart your network using the app. Even

I have had 3 Nest locks for about 2 years and never had a problem. Just
this week however, all 3 locks have been going on and off line a few
times a day. Wondering if it may be a software update issue....
