PHP Cross-Origin Request Blocked - php

Question

just wanted to find a solution to this. I am within System A and I make the following call
$("#page-form").submit(function(event){
$.ajax({
type: "POST",
url: "https://someOtherUrl/process.php",
data: {
'mobNumber': $("#mobile").val()
}
}).done(function (response) {
alert(response);
});
})
Now this makes a call to a PHP file on another server. This PHP file does nothing at the moment, I simply have
<?php
header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Methods: PUT, GET, POST");
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");
var_dump("1");
However I am getting a cross origin request blocked error. Why would this be happening?
As a side note, I have no access to the server running System A, so it has to be done on my server where the PHP file sits.
Thanks

Try this in the .htaccess file present at the root folder on https://someOtherUrl/ :
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
</IfModule>
