title: $facebook->api() call returns CurlException: 7?
body: <p>After authorizing my app, I'm redirecting the user to my php-script:</p>
  
  <pre><code>require 'facebook.php';
  
  $facebook = new Facebook(array(
      'appId'  =&gt; 'XXX',
      'secret' =&gt; 'XXX',
  ));
  
  $user = $facebook-&gt;getUser();
  $fbUser = $facebook-&gt;api('/me');
  </code></pre>
  
  <p>The getUser()-Function properly returns my Facebook-UserID, but as soon as I am trying to fetch further information with $facebook->api('/me'), the following error-message is returned:</p>
  
  <blockquote>
    <p>Uncaught CurlException: 7: couldn't connect to host thrown in /XXX/base_facebook.php on line 886</p>
  </blockquote>
  
  <p>Strange thing is, that the exact same code has been working for months on the very same server?!</p>
