Hello all
I am desperately trying to get my my Home Assistant and Google Home linked again.
I created everything new from scratch and now in the google home app when I try to add my [test] service, I get to the login screen from my home assistant and after clicking Login, I get “An error occured. Please try again” in the app and nothing gets linked.
I tried all possible configurations for the google_assistant, even only just specifying a project_id and api_key. Nothing helps, always the same error This did work once when I created it about a year ago. I wanted to update the devices which didn’t work so I tried re-linking and now everything is gone.
My setup is:
HomeAssistant (latest) in docker in an ESXi-Ubuntu VM
Reverse Proxy on a Synology NAS with let’s encrypt certificates
External Domain with correct forwarding.
What is kind of special is that I am in a double-NAT scenario which I think can lead to problems when a device from he intranet tries to contact another device in the intranet by the external address. I fixed this by using my own internal DNS which forwards external addresses to my local addresses when used locally. To get google home to use that dns, I blocked port 53 UDP/TCP to ip 8.8.8.8 and 8.8.4.4 from the google home devices. Not sure if that is needed all all though.
I would really appreciate some help as I don’t know what else I can try. Also I cannot find any log messages in google home app or on HA.
Thanks a lot for your support
Roman
