Facebook oAuth in asp.net Webform

Hello everyone, 

I am trying to integrate Facebook oAuth into my asp.net application

I am using the code example from http://onlinewebapplication.com/facebook-login-sign-in/

I have inputted my appkey & secret on the oAuthFacebook.cs

When I go to my login page and click on the "Login via Facebook" button, one of 2 things happens

1) I get a timeout error on webRequest.GetResponse().GetResponseStream().Close();

OR

2) I get redirected to a page with the url like bellow, and it stops. No login happens
