Same issue..

Did you added https://my.home-assistant.io/redirect/oauth under Authorized redirect URIs when creating the OAuth client ID?

Had the same issue, this fixed for me.

PS. You'll need to restart HA to have Google Drive option in the backup location page.

I added https://my.home-assistant.io/redirect/oauth but still I get the error when trying to connect:

Thanks @tronikos, it worked! Maybe it should be added to the docs?

On one of my installation it worked without adding a Test user.

Just followed the steps from "Scenario 2: You do not have credentials set up yet" and worked without issues.

Thanks I discovered the error - did not "publish"...

Missed
10. Select OAuth consent screen again and under Publishing status, select Publish app.
Otherwise your credentials will expire every 7 days.
11. Make sure Publishing status is set to In production.
