Until a month ago my IPN set up worked fine since many years!
But now it doesn't work anymore.
Is there any substantial change that I have missed?
Thanks!
This is part the PHP code that worked fine for me:
$header = "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
$fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30);

Sometimes, it's as simple as updating the 1.0 in your script to 1.1. Give that a try and see if it helps. If not you'll need to dig a little deeper in your server to ensure it supports HTTP 1.1.

Thanks, changing from http 1.0 to http 1.1 finally worked. However I kept trying resending an IPN and it did not solve the problem after the change. Only after initiating a new IPN things are working as expected.
Now it seems to be working fine again.
Thanks!
