MVC google login - OpenID auth request contains an unregistered domain

Question

When I try to login today via google in my web app, I get that error:

400 That’s an error.

OpenID auth request contains an unregistered domain: http://XXX.XXX.XXX/ (IP here)

But on localhost everything works fine. What is more - on other project also everything works nice.

I'm using default OAuth:

OAuthWebSecurity.RegisterGoogleClient();

How to resolve it?

Answer 1

This approach is obsolete as Google changed their auth to OAuth2

I didn't delete this answer because formerly approved api users are still valid to use.

== Original post below ==

If you are OWIN-based MVC5 user, just change Startup.Auth.cs file

        app.UseGoogleAuthentication();

to

app.UseGoogleAuthentication(
 clientId: "000-000.apps.googleusercontent.com",
 clientSecret: "00000000000");

according to the http://www.asp.net/mvc/tutorials/mvc-5/create-an-aspnet-mvc-5-app-with-facebook-and-google-oauth2-and-openid-sign-on page.

Answer 2

Google has disabled OpenID2 for new domains. Existing relying parties can continue to use the API at least until the end of the deprecation period that runs through to April 2015. The announcement is at: https://developers.google.com/+/api/auth-migration#timetable
