Error: Unable to sign in because of an error from Auth0. (Access denied.)

Steps:

1. I click Use your GitHub account to authenticate so you can manage your Auth-Key.
2. I click the Github black button inside the Auth0 login widget.
3. I click in Github the green button: Authorize peterbe. Peterbe.com is successfully added to my Authorized OAuth Apps list when checked later.
4. I get a danger alert with the message: Unable to sign in because of an error from Auth0. (Access denied.).

I see in Chrome devtools I got redirected to this URL after the autorization:

https://peterbecom.auth0.com/login/callback?code={code here}&state={code here}

and then it redirects to:

https://autocompeter.com/auth/callback?error=unauthorized&error_description=Access%20denied.

I think this is abandoned.
