WEB API Google Authentication access denied

Question

I am trying to use google authentication API to have a google log-in on my web API project. Created the OAuth

and I enabled the Google+ API

added the Client ID and Client Secret on my Startup.Auth

app.UseGoogleAuthentication(new GoogleOAuth2AuthenticationOptions()
        {
            ClientId = "497652290327-gd5h0lrheuqcrtccp2c4rqi8dt5vpfb8.apps.googleusercontent.com",
            ClientSecret = "sPGGSo2d7VZX7YnRNGmCPQDv"
        });

but when I try to log in the URI dispalys

http://localhost:54388/#error=access_denied

It consued me because I followed every steps from the tutorial of kudvenkat but still encountered this error. Did I do something wrong

Note that the credentials that I am using on this google log in does not exist on my database (if that matters)

Answer 1

Ensure that you have the lastest OWin / FacebookAuth Nuget packages and that your application has a valid connection string to a SQL database with migrations applied if using code-first. Also check that the clientID & secret are correct, on the google apis console it should show some traffic on the client app
