For several months now we have had two Nest Minis having issues connecting to Google with the typical error responses
Having completed the troubleshooting at https://support.google.com/googlenest/answer/10248641?hl=en already numerous times, we were hoping to get some real help here.
We have not only performed the suggested troubleshooting steps, but have also upgraded our internet service, as well as the router and modem, and again completed the troubleshooting steps with no success. It still like clockwork will give one of the above mentioned error responses three times before working. Also, once it starts working, as long as you do not let it sit without interacting with it for several minutes, it will continue to work perfectly fine. It is only after it sits for some time that it goes back to the error
Thanks for reaching out. Sorry to hear about your experience with your Google Nest Mini. I'd love to dig deeper into this.
To eliminate network issues, please try setting up your device using a mobile hotspot. Please note that you will need two mobile devices for this setup (one will serve as a router and the other to be used to set up your Nest Mini).
Let me know how it goes.
