title: Failed to connect to www.googleapis.com port 443: Network unreachable
body: <p>I'm trying to implement google sign-in in my website that is written in Symfony2 using <a href="https://github.com/google/google-api-php-client" rel="nofollow">Google Client API</a>. I followed the instructions <a href="https://developers.google.com/+/web/signin/server-side-flow" rel="nofollow">here</a>, but when I call $client->authenticate($code); command an exception is thrown telling that:<br> Failed to connect to www.googleapis.com port 443: Network unreachable <br>
  What is the problem?</p>
