I’m at the last step of adding the Nest integration and get the message: " Access blocked: This app’s request is invalid", Error 400: redirect_uri_mismatch.
In the detail, I get, redirect_uri=https://xxxxx.duckdns.org:8123/auth/external/callback. However, in the Oauth credentials, I specified “Link to OAuth2 Authorize Callback – My Home Assistant” for the Authorized redirect URIs field.
Any help would be appreciated!
