Python Post Request works, but the same PHP (CURL) does not work

Question

I was trying to write the same post request via php as i did in python. In python it works well, while in php it does not even reach the server at all. This is php 7.4. Also I can access the server http://someip:2080/api/ via browser. So http://someip:2080/api/ is a public IP, I can even access via browser, so it should work from anywhere.

PHP code:

$payload = array(
'data' => 'data0',
);

// Setup cURL
$ch = curl_init('http://someip:2080/api/');
curl_setopt_array($ch, array(
CURLOPT_POST => TRUE,
CURLOPT_RETURNTRANSFER => TRUE,
CURLOPT_HTTPHEADER => array(
    'Content-Type: application/json'
),
CURLOPT_POSTFIELDS => json_encode($payload)
));

$response = curl_exec($ch);


if($response === FALSE){
   die(curl_error($ch));
}

and python code:

import requests
import json
headers = {'Content-Type': 'application/json'}
resp = requests.post("http://someip:2080/api/" , data = json.dumps(allparams),  headers=headers)
thepara = resp.json() 

I have no idea what is wrong I tried around 10 ways to make post request from php and nothing worked.

The problem was that the port 2080 was already occupied on a cpanel. So the solution is to :

1. Change port to lets say 9999 which is not occupied
2. Allow the port in WHM firewall, under IPv4 Port Settings (in WHM - ConfigServer Security & Firewall ) or tell admin to do this for you.
