so I've been building this project and the IPN worked perfectly for my Sandbox - but as soon as I changed the URL to live, I got this log message.
I tried using this as a solution but still receiving the error.
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: Close', 'User-Agent: company-name'));
The Message response I get is
<HTML>
<HEAD>
<TITLE>Access Denied</TITLE>
</HEAD>
<BODY>
<H1>Access Denied</H1>
You don't have permission to access "https://www.paypal.com/cgi-bin/webscr" on this server.<P>
Reference #18.........

The IPN im using is this one :
