403 error when using google authentication

[Strandedpirate]

Getting a 403 forbidden error while using the google authentication when the EnsureSuccessStatusCode method is called. I get to the "allow" screen on google's side, I grant my app access to my account but then it bombs out after redirecting back to my app. I tried setting the TokenEndpoint to "https://accounts.google.com/o/oauth2/token" instead of the hard-coded default but it didn't help; same error.

What else can I try to resolve this?

The facebook authentication has the same status code check and it is working just fine.

My setup:

app.UseGoogleAuthentication(new Microsoft.AspNet.Authentication.Google.GoogleOptions
{
    SignInScheme = CookieAuthenticationDefaults.AuthenticationScheme,
    ClientId = Configuration["OAuth:google:clientid"],
    ClientSecret = Configuration["OAuth:google:clientsecret"],
    CallbackPath = new PathString(Configuration["OAuth:google:callbackpath"]),
    AutomaticAuthenticate = true,
    AutomaticChallenge = true,
});

Error:

An unhandled exception has occurred: Response status code does not indicate success: 403 (Forbidden).
      System.Net.Http.HttpRequestException: Response status code does not indicate success: 403 (Forbidden).

Thanks, for me it was a simple matter of enabling Google+ API.
