Google Assistant Linking issues (Version 0.77.2) - 405 error

[datamonkey (Roland)]

Hi @mitch
the relinking seems to work now. At least I get a screen popping up that has “Account now linked”
but after that the Google Home app has some issue. “Can not update settings …”
And then it all starts again.
I found an old post of mine where I had the 405 error, maybe it helps you:

Setting up Google Actions for Assistant

Hi, I am very excited about this new component. I am running 0.55.2 in a docker on unRAID. Have copied the files into custom_components and the http/__ init.py __ file as well. Then I followed the instructions and created the app. It shows up for testing in Google Assistant. But when I open it I only get: 405: Method Not Allowed No logs and no errors that I can see. Any idea where to go next?

and the answer:

@datamonkey Step 6.3 3. Authorization URL (replace with your actual URL): `https://[YOUR HOME ASSISTANT URL]/api/google_assistant/auth You probably misspelled the url, don’t forget the « auth » part at the end.
