I have the following PHP code which simply grabs a URL behind HTTP-Basic authentication and re-serves it:

```
<?PHP
    header("Content-Type: text/xml");

    $username = "username";
    $password = "password";
    $url = "http://s6.voscast.com:7158/admin.cgi?mode=viewxml";

    $context = stream_context_create(array(
        'http' => array (
            'method' => "GET",
            'header' => "Authorization: Basic ".base64_encode($username.":".$password)."\r\n".
                        "User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.1 (KHTML, like Gecko) Ubuntu/11.04 Chromium/14.0.835.202 Chrome/14.0.835.202 Safari/535.1"
        )
    ));

    print file_get_contents($url, false, $context);
?>

```

It works without any issues locally on my Linux Mint 11 machine (v. 5.3.5), but fails on another Linux server of a client which is running 5.2.14:

It seems like it's trying to validate the XML, which is totally unnecessary. Is there a way I can disable this feature or investigate further as to what's going wrong? 

When I look at the source of the response, I see the following:

> 
> failed to open stream: Connection refused in **/home/livshin/public\_html/wp-content/uploads/\_radio/songinfo.php** on line **16**  
>

It's working fine locally, but is failing online? How can I further debug this?
