Help!! XML-RPC Issues.

[eluser]Unknown[/eluser]
I am trying to code for PayPoint's (formally SecPay) API within CodeIgniter. I am following along their sample code here: http://www.paypoint.net/support/gateway/...mlrpc-php/

Here is what I have so far.

controllers/paypoint.php

Code:

<?php

Class Paypoint extends CI_Controller {

    function __construct() {

        parent::__construct();

        // Load default libraries
        $this->load->library('xmlrpc');

    }

    function index () {

        $this->xmlrpc->server('https://www.secpay.com/secxmlrpc/make_call', 443);
        $this->xmlrpc->timeout(60);
        $this->xmlrpc->method('SECVPN.validateCardFull');

        $request = array(
            array('secpay', 'string'),
            array('secpay', 'string'),
            array('trans_id', 'string'),
            array('123.132.321.132', 'string'),
            array('Mr Jo Bloggs', 'string'),
            array('4444333322221111', 'string'),
            array('10.51', 'string'),
            array('12/10', 'string'),
            array('', 'string'),
            array('', 'string'),
            array('', 'string'),
            array('', 'string'),
            array('', 'string'),
            array('test=true,dups=false', 'string')
        );

        $this->xmlrpc->request($request);

        if ($this->xmlrpc->send_request()) {
            echo '<pre>';
            print_r($this->xmlrpc->display_response());
            echo '</pre>';
        } else {
            echo $this->xmlrpc->display_error();
        }

    }

}

But the output is always: 'No data received from server.'

Am I doing something wrong?
