New #access_denied with Facebook Login (ASP.NET MVC)

Question

I am having a strange problem with Facebook Login on my website. This is something completely new, the Facebook login has always worked correctly, and it is still working on my Android and iOS App.

I have a link on the site, for example:

 http://myURL/api/Account/ExternalLogin?provider=Facebook&response_type=token&client_id=self&redirect_uri=http://myURL/Home/Register?

Obviously, everything is set up in developer.facebook.com, as in OAUTH ADDRESS I have:

 http://myURL
 http://myURL/Home/Register
 http://myURL/Home/Register?

And I also have my localhost (which worked correctly from two days ago)

My application requires this access:

       var facebookAuthenticationOptions = new FacebookAuthenticationOptions()
        {
            AppId = "[Hidden For Security Reason]",
            AppSecret = "[Hidden For Security Reason]"
        };
        facebookAuthenticationOptions.Scope.Add("email");
        facebookAuthenticationOptions.Scope.Add("user_friends");
        facebookAuthenticationOptions.Scope.Add("user_birthday");
        app.UseFacebookAuthentication(facebookAuthenticationOptions);

My chart api version v2.6

When I click the link, I get to facebook, I paste my credentials, and it returns me to myURL # access_denied.

Are there any clues?
