WiFi connectivity for thermostat

[Kkendall1]

All of a sudden one of my thermostats lost connectivity w wifi. I have restarted the network and it’s fine. I restarted the thermostat as the online help suggested and nothing. Any ideas. By the way the other two are doing fine

I just started having the same issue with one of my thermostats. Not sure how to fix this.

I am having the same exact problem. Why are the Nest thermostats not connecting to wifi? If it's a system error I hope it gets fixed soon. Now I will have to set it manually. SMH.

Mine as well. It won’t charge and it’s not turning my heat on. I am over NEST rn.

Appears to be a major issue introduced with the latest firmware update.
