Redirect URI invalid origin

Trying to get integrated with GMail and when I am adding the URI for the authorized JavaScript origin (https://connect.wpmailsmtp.com/google) I am receiving an error from Google that says: Invalid Origin: URIs must not contain a path or end with “/”.

If I remove the /google at the end it will accept the value, but when I try to Connect to Google, I receive this error:

Authorization Error
Error 400: redirect_uri_mismatch

You can't sign in to this app because it doesn't comply with Google's OAuth 2.0 policy.

If you're the app developer, register the redirect URI in the Google Cloud Console.
