Nest integration suddenly stopped working

Configuration
1

A few days ago my thermostats suddenly stopped working through home assist. Troubleshooting online suggested removing the integration and setting it up fresh. But now I can get them added back. I’ve run out of things to try so I’m hoping someone has suggestions for what I can try next. Here are the logs related to the issue.

I assume this isn’t applicable?

It’s a few weeks early though.

Switch away, nest is soon turning off the integration capabilities. I got rid of it an purchased the ecobee smart thermostat enhanced. It is completely local access through the homekit integration - and much more reliable than the Nest even ever was. I got it at a deep discount by using my local power utility’s online store.

We should verify the OP’s Nest gen type before jumping to conclusions.

Gen 1 and 2 are pre 2013 and simply looking at the model # in the Nest app will identify the gen.

For example Display 3.7 is Gen 3 with the 3 as the gen identifier.

I have two thermostats. One is 3.7 the other 3.4

Then the end of support does not apply to your issue or devices.

Do you mean can’t?

Yes sorry, I can’t get them added back.
