Failed to connect to curl URL - php

Question

I am unable to connect with the Curl URL using PHP.
Below is my code, that I am trying to execute.
$url="http://b2b-dev.cenveo.com:6700/dmz/EZComm?fromTp=DiscountLabelsCustomer&toTp=DiscountLabels&operationID=DiscountLabels/1.0/PurchaseOrderRequest";
$xml_content = '<?xml version="1.0" encoding="utf-8"?><Order xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.discountlabels.com http://www.discountlabels.com/DLI_INTGR.xsd" SubmittedDate="2017-12-06 02:52:43" xmlns="http://www.discountlabels.com"><Customer><Name>Cmagnets</Name><PSCustID>987654</PSCustID></Customer><BlindDropshipAddress AddressID=""><Name></Name><Attention></Attention><PostalAddress><Address1></Address1><Address2></Address2><City></City><State></State><PostalCode></PostalCode><Country></Country></PostalAddress><Email></Email><Telephone><PhoneNumber></PhoneNumber></Telephone>

$ch = curl_init();
url_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION,FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER,FALSE);
curl_setopt($ch, CURLOPT_SSLVERSION, 3);
curl_setopt($ch, CURLOPT_ENCODING, 'identity');
curl_setopt($ch, CURLOPT_FRESH_CONNECT, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_setopt($ch, CURLOPT_HTTPHEADER,array("Content-Type: application/xml", "Accept: application/xml"));
curl_setopt($ch, CURLOPT_FAILONERROR, false);
curl_setopt($ch, CURLOPT_TIMEOUT, 10); //times out after 4s
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_content); // add POST fields
curl_setopt($ch, CURLOPT_POST, 1);
$output = curl_exec($ch);
print_r($output);
if (curl_errno($ch)) {
echo 'Error: ' . curl_error($ch);
}
After Executing the above code I am getting the below Error message.
Error: Failed to connect to b2b-dev.cenveo.com port 6700: Connection refused.
Thanks in advance

Either you're missing some headers, or you have to whitelist your server's ip address with cenveo. There is no error related to curl, just the opposite server denying your connection.
