Can't get this working out of the box : missing redirect_uri parameter and Stream has been reopened after close about oauth2client HOT 1 OPEN

@kotancode the 191 error is produced by Facebook. It seems you didn't specify your redirect URI correctly with their system. Maybe this StackOverflow issue might help you with that: http://stackoverflow.com/questions/4691782/facebook-api-error-191

The error occurs inside the part or the oauth client that transparently handles the toke exchange. If the connection fails it will be automatically retried up to 4 times before an error callback is called. If it still fails the oauthClient:didFailToGetAccessTokenWithError: method of the NXOAuth2ClientDelegate should be called.
