UPDATE
I am having a degree of success connecting to the server with fsockopen. However, I would like to use cUrl if possible.

I am trying to make a request to flask using curl in the form of a post. The goal is not to use jQuery but to achieve more separation and validation of information. Despite being able to make a request from my desktop, I cannot make a request from my web server. I have iptables running and have listed the rules below. Also, I have listed the PHP code. I am not receiving any output from flask at all.
Technology:
Go Daddy Hosting account where the request is made
Go Daddy vps for the flask server
Iptables:
ACCEPT all -- c-xxx.xxx.xxx anywhere
ACCEPT all -- ip-xxx.xxx.xxx anywhere
The ip listing is from the web server but the c listing is from my desktop.
Curl Request from PHP
$ch=curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_TIMEOUT, 400);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, True);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, True);
curl_setopt($ch, CURLOPT_PORT, 8888);
curl_setopt($ch, CURLOPT_POST, count($data));
curl_setopt($ch, CURLOPT_POSTFIELDS, array('url'=>'login','user'=>$user,'pass'=>$pass,'auth'=>$authstring,'ip'=>$ip));
$result = curl_exec($ch);
This request is not even registering with tcpdump -i eth0 port 8888 unlike the requests from my desktop. The ip addresses are correct.
The request is working in Aptana.
The specific error is:
* Rebuilt URL to: xxx.xx.xx.xx/
* Hostname was found in DNS cache
* Trying xxx.xx.xx.xx...
* connect to xxx.xx.xx.xx port xx failed: Connection refused
* Failed to connect to xxx.xx.xx.xx port xx: Connection refused
* Closing connection 8
This is after completely flushing my iptables. In Aptana with the same php version, I get:
Trying xxx.xx.xx.xx...

* Adding handle: send: 0
* Adding handle: recv: 0

Unfortunately, a hosting representative from GoDaddy told me that only the following ports are open to me. 80, 21 ftp, 22 SFTP, 445 ssl, 3306 mysql. Basically, I cannot send anything. I had to switch hosting services. A VPS from Go Daddy works too.
