Google assistant Component - cant add service through google home app!

Hey Guys,

So i followed the Google assistant component guide: https://home-assistant.io/components/google_assistant/

In one of the final steps where i should be able to connect through the google home app i recieve this error message:

Anyone know where i shall start looking and how to fix?

It may be you need to map your port 443 to port 8123 ( or wherever your HA lives).
I ran into the same problem but got around it by adding :8123 into my authorisation url. I can’t map my internal ports as I’m using UK sky router which doesn’t have the option. And I think I’m stuck at the next step due to that fact.
