是否阻止了与特定端口的传出连接？

I have bought a linux server from Godaddy . I tested to connect and get response from remote server , but it says CURL Failed . Also , it doesn't work on Node app too .

Here is the PHP Code :

<?php 
$url = 'http://dev.api/pay';
$ch = curl_init();
curl_setopt( $ch, CURLOPT_URL, $url );
curl_setopt( $ch, CURLOPT_POST, true );
curl_setopt( $ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_POSTFIELDS, "<xml>here</xml>" );

curl_setopt($ch, CURLOPT_PORT, '9085');

$result = curl_exec($ch);
$output = curl_getinfo($ch);

echo "<pre>";
var_dump($output);
echo "</pre>";

curl_close($ch);

var_dump($result);

. Actually this code is working on localhost , but it doesn't work when accessed from the server. If the outgoing connection is being blocked from the server's firewall i rented , how can i disable it or allow that port i intended to use only ?

Do you have root access? if so, use iptables to remove outgoing connection block.

If you do not have root acces, your host just does not allow outbound connections and there is nothing you can do about it.
