I have a 2nd gen nest thermostat that has worked reliably for years. It went offline 4 days ago - not able to access it through android app or web client. I have rebooted the device and successfully found my router in setup. It appears to connect. But I cannot reinstall it on the nest app or through google home. When I ask for an entry key it times out. The network itself is used by several other devices and there are no connection issues with my desktop windows pc or my android phone. What could be going on?
Thanks for posting and sorry for the delay. I want to dig deeper into your concern.
A few questions — when it times out, do you get a specific message or a code? If yes, what is it? Also, do you still see the thermostat on your Nest app?
I'll look forward to your response.
Thanks for these added details.
Are you seeing on your thermostat display that it is connected to WiFi but is showing offline on your Nest app? If yes, is it possible to reset the Account connection settings of your thermostat so that it would forget the WiFi and account it is connected to? That way, it would be able to provide an entry code for you to continue setting it up again. Here's a guide: https://bit.ly/2Oai5yw
