Google Nest not working

Hi guys.
I was trying to connect Home Assistant to my Google Nest (Thermostat), i followed step-by-step every instruction and when i tried to link my Google Account it gave me an error (See screenshot for details).
I saw the “Troubleshooting” section and tried to fix it but nothing.
Can anyone help me please? Hope you reply :))

I am also having issues. My error rate went up to 100% and I am no longer getting doorbell notifications.
