Php Curl live server not working

Question

I test the script on my localhost and it working perfectly. I tried on my the live server and it didn't work.

<?php
   $uploadfile=dirname(__FILE__)."/xml_request/cat.xml"; 
   $ch = curl_init("http://remote.xxxxxxxxxx.com.au:8090/Options.API");   
   curl_setopt($ch, CURLOPT_POSTFIELDS,
               array('Request'=>"@$uploadfile",
                     'clientKey'=>'xxxxxxxxxxxxxxxxxxx'));
   curl_setopt($ch, CURLOPT_PORT, '8090');
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
   $postResult = curl_exec($ch);

   $response = curl_getinfo($ch);
   echo "<pre>";
   print_r($response);
   echo "</pre>";

   curl_close($ch);
   echo "<pre>";
   print_r($postResult);
   //file_put_contents(dirname(__FILE__).'/xml_record/live.xml', $postResult);

?>

Localhost I print_r the curl_getinfo($ch).

Array
(
    [url] => http://remote.xxxxxxxx.com.au:8090/Options.API
    [content_type] => text/html; charset=utf-8
    [http_code] => 200
    [header_size] => 246
    [request_size] => 215
    [filetime] => -1
    [ssl_verify_result] => 0
    [redirect_count] => 0
    [total_time] => 2.278
    [namelookup_time] => 0
    [connect_time] => 0.344
    [pretransfer_time] => 0.344
    [download_content_length] => 9376
    [upload_content_length] => 759
    [starttransfer_time] => 0.734
    [redirect_time] => 0
    [certinfo] => Array
        (
        )

    [redirect_url] => 
)

Live test I print_r the curl_getinfo($ch).

 Array
    (
        [url] => http://remote.xxxxxxxxxxx.com.au:8090/Options.API
        [content_type] => 
        [http_code] => 0
        [header_size] => 0
        [request_size] => 0
        [filetime] => -1
        [ssl_verify_result] => 0
        [redirect_count] => 0
        [total_time] => 0.012024
        [namelookup_time] => 0.011809
        [connect_time] => 0
        [pretransfer_time] => 0
        [download_content_length] => -1
        [upload_content_length] => -1
        [starttransfer_time] => 0
        [redirect_time] => 0
    )

Not sure if the port of the url is the problem. I try to search to solve the problem but no luck.

From Comments:

Your webhost is probably blocking outbound traffic on port 8090. Many webhosts block uncommon ports for added security. The only way to get this resolved is to contact your webhost and ask them to unblock the port so that you can connect on it.
