Google Home error for Nest Thermostat

[Lesia]

I'm trying to set up Nest on my phone. When I open Nest app it directs me to Google Home to add device. After I'm almost done, it says Connected on my phone, and in a second I get an error over the Connected message, saying "Something went wrong. We couldn't save your changes. Try again."

But I tried like 20 times now.
