Question

This is the FB Url I am trying to access.
https://graph.facebook.com/oauth/authorize?client_id=694aa71aed60fb9d79aae04b81ff27c8&redirect_uri=http://localhost/TestConnect/Facebook.aspx&scope=email,user_about_me,user_interests,user_likes,user_location,user_notes,user_education_hi

It says
The page cannot be displayed
There are too many people accessing the Web site at this time.
It was working fine until last night
Even when I type it in the browser, it has no response. All it shows me is a green progress bar even after 20min

What should I do?
Thanks

Here is your URL :

https://graph.facebook.com/oauth/authorize
?client_id=694aa71aed60fb9d79aae04b81ff27c8
&redirect_uri=http://localhost/TestConnect/Facebook.aspx
&scope=email,user_about_me,user_interests,user_likes,user_location,user_notes,user_education_hi

When changing redirect_uri to http://localhost it works fine for me. So I guess it is your page http://localhost/TestConnect/Facebook.aspx that does not works fine.

The redirect_uri will be called with GET parameters, be sure to handle them correctly :

• If the user allows your app, he will be redirected to :

  http://localhost/TestConnect/Facebook.aspx?code=...
  

  and you will need to get a ask an access token to facebook with that code (the code parameter) by calling :

  https://graph.facebook.com/oauth/access_token
     ?client_id=YOUR_APP_ID
     &redirect_uri=YOUR_URL
     &client_secret=YOUR_APP_SECRET
     &code=THE_CODE_FROM_ABOVE
  

• If the user doesn’t allow your app, he will be redirected to :

  http://localhost/TestConnect/Facebook.aspx
     ?error_reason=user_denied
     &error=access_denied
     &error_description=The+user+denied+your+request.
  

  so you can detect that error by testing the get parameter error.

Hope that helps !
