cURL development load slowly after uploaded in server PHP - php

Question

Hi "I would like to ask an assistance" yes, you read it right, I don't know what's happening to my cURL development program. Straight to the point, I have cURL development program which works perfect and faster in my localhost xampp, I even receives a response correctly. But I thought i'm done on my work, until I uploaded it to my cpanel, It became superslow in terms loading, It cannot receives any response anymore also after loading.
I just receive
Curl Error: 7
OR
Curl Error: 28
I don't know whats this weird thing. I googled already the errors (cURL error(7) "It says connection issue to host, but its impossible, I can connect to host in my localhost." cURL error: 28 I have made some adjustment also to my curl_opt() you see in my comment below.
Here's my code
$headers = array(
// "Accept-Encoding: gzip, deflate",
"Content-Type: text/xml;charset=\"UTF-8\"",
"SOAPAction: \"http://domain.org/\"",
"Host: domain.com",
"Content-length: ".strlen($xml_post_string),
);
$url = $soapUrl;
// PHP cURL for https connection with auth
$soap_do = curl_init() or die('Error');
set_time_limit(0);
curl_setopt($soap_do, CURLOPT_URL, $url);
curl_setopt($soap_do, CURLOPT_CONNECTTIMEOUT, 0);
curl_setopt($soap_do, CURLOPT_TIMEOUT, 400);
curl_setopt($soap_do, CURLOPT_AUTOREFERER, true); // try, to solve an issue
curl_setopt($soap_do, CURLOPT_MAXREDIRS, 10); // try, to solve an issue
curl_setopt($soap_do, CURLOPT_FOLLOWLOCATION, true); // try, to solve an issue
curl_setopt($soap_do, CURLOPT_TIMEOUT_MS, 400); // try, to solve an issue
curl_setopt($soap_do, CURLOPT_RETURNTRANSFER, true );
curl_setopt($soap_do, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($soap_do, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($soap_do, CURLOPT_POST, true );
curl_setopt($soap_do, CURLOPT_POSTFIELDS, $xml_post_string);
curl_setopt($soap_do, CURLOPT_VERBOSE, TRUE);
curl_setopt($soap_do, CURLOPT_HTTPHEADER, $headers);
But still the same, No response coming and loads slow

Answer 1

Whenever I run into problems with cURL, I place the curl handle that has just completed to PHP's curl_getinfo function.
Try adding this code just after you run curl_exec($soap_do);
echo '<pre>'; print_r(curl_getinfo($soap_do)); echo '</pre>';
curl_getinfo returns an array of data, which is displayed by print_r, and formatted in an easy to read list by the <pre> tag.
