Błąd połączenia z API DirectAdmin

Mam problem z połączeniem się poprzez API DirectAdmin.
Pojawia m się taki komunikat:

Creating user Reseller on localhost.... 
Error Creating user Reseller on server localhost:

Kod:

<?

include 'httpsocket.php';

$server_ip="localhost"; //IP that User is assigned to
$server_login="admin_kliknijl";
$server_pass="pass";
$server_host="91.239.67.99"; //where the API connects to
$server_ssl="N";
$server_port=2222;


if (isset($_POST['action']) && $_POST['action'] == "add")
{

	$username=$_POST['username'];
	$domain=$_POST['domain'];

<form action='reseller.php' method="POST">
<input type=submit name=action value="add">
Username: <input type=text name=username><br>

**Note:  do not use this php file exactly as it is.  It's only to demonstrate the basics of the api.
You *must* do form checking to ensure safe values are passed.
Also, it's a really bad and very insecure practice to put a form like this publicly on your website for anyone to use.
If you do, you'll end up with a server full users you did not create (this script creates accounts without any involvment with an admin: bad)

Co jest nie tak?
