Facebook application development Fatal error: Uncaught CurlException: 28: connect() timed out! thrown in

PHP SDK 3.1
 

it means : your web hosting is not able to connect to Facebook quickly.

Solution is Simple.

you have 2 choices :

1) change your hosting plan or change your web hosting

-OR-

2) go to base_Facebook.php file

line # 128 : with those lines

 public static $CURL_OPTS = array(
    CURLOPT_CONNECTTIMEOUT => 10,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_TIMEOUT        => 60,
    CURLOPT_USERAGENT      => 'facebook-php-3.1',
  );

Change the (CURLOPT_CONNECTTIMEOUT => 10,) into (CURLOPT_CONNECTTIMEOUT => 30,) .... save the base_facebook.php .

That is it ....
