fsockopen in php not working on server

Question

Here is my code:

$fp = fsockopen("74.63.172.37", 22, $errno, $errstr, 50);

if (!$fp) {

    echo "not connected";

} else {

    $out = "GET / HTTP/1.1\r\n";
    $out .= "Host: 74.63.172.37\r\n";
    $out .= "Connection: Close\r\n\r\n";
    fwrite($fp, $out);
    $val = "";
    if (!feof($fp)) {
        echo "<br/>".fgets($fp, 128);
    }

    if (feof($fp)) {
        echo "<br/>Not connected";
    } else {
      echo "<br/>Connected";
    }

    fclose($fp);

    die();
}

On local server it gives me an output:

trying to connect
SSH-2.0-1.82_sshlib GlobalSCAPE
Connected

Whereas on server it gives me an output:

trying to connect
Not connected

I have another sftp server, where I could connect from both server and locally. What could be the issue?

Thanks ,, I found the solution. Destination Host has blocked my Server IP address.
