Inside your IPN, you are opening a socket to www.paypal.com instead of www.sandbox.paypal.com

You need to have OpenSSL enabled in your php config

I recently experienced this problem, going from a code base that hadn't changed and was working correctly on the Paypal sandbox.

If you can provide more information was to what is occuring, i can point you more in the right direction. I'd suggest doing what's been talked about in that post first. Which is simply adding the new header.

$header .= "Host: www.sandbox.paypal.com\r\n";

Just be aware not to have this header on a production system.

Hope this helps. If it doesn't resolve your issue, use var_dump line 39 to see what the responses are.

I've posted a more detail response in a different topic which outlines debugging in an easier manner : Paypal IPN Integration into PHP
