Trouble Integrating Google Home with Home Assistant

Hello everyone,

I am trying to control all the devices configured in my Google Home through Home Assistant. I watched this tutorial:

After completing the initial steps and entering the OAuth client ID and secret in the correct place in HA, I am receiving an “access denied” message.

I entered Link to OAuth2 Authorize Callback – My Home Assistant
To Authorized redirect URIs as the URL as instructed in the settings.

Can anyone point out what might be the problem?

Thank you!
