卷曲：PHP KO，cmd好的

I need some help, here the code :

<?php
    $curl_options = array (CURLOPT_RETURNTRANSFER => true,
        CURLOPT_HEADER => true,
        CURLOPT_FOLLOWLOCATION => false,
        CURLOPT_ENCODING => "",
        CURLOPT_CONNECTTIMEOUT => 30,
        CURLOPT_TIMEOUT => 60,
        CURLOPT_MAXREDIRS => 5 );


    $handle = curl_init("http://my.awesome.subdomain.com");

    curl_setopt_array($handle, $curl_options);


    $content = curl_exec($handle);

    print_r(curl_error($handle));

    print_r($content);
    die();

my.awesome.subdomain.com is a vhost. On the same machine i have another.awesome.subdomain.com which is on the same machine.

Via SSH, if i do $> curl my.awesome.subdomain.com I get the answer i expect. But when i use this code, i get "Connection timed out after 30180 milliseconds"

Thanks for help and sorry for my writing errors.
