Hi In the past couple of days, our PayPal IPN has stopped working and receiving a empty response from PayPal. Nothing has changed on the server or in our code. Attempting to cUrl to the PayPal IPN url simply returns an empty response. ``` $url = "https://www.paypal.com/cgi-bin/webscr?cmd=_notify-validate"; $ch = curl_init($url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_FRESH_CONNECT, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13'); $data = curl_exec($ch); curl_close($ch); print $data; ``` The above should return "INVALID" and works as expected on my localhost and from other servers. Changing the url to any other domain other then PayPal also works without issues. So it seems it only received the empty response from paypal.com I wonder if any one has run into the issue or could give pointers where to look in the hope to- resolve it? Kind Regards Musaffar
