I'm getting the the following error when trying to verify payments using the IPN. The same code was tested on the sandbox (before and after the error) and is verifying properly.

The code I'm using is as follows:
$raw_post_data = file_get_contents('php://input');
pplog("Processing POSTed data");
$raw_post_array = explode('&', $raw_post_data);
$myPost = array();
foreach ($raw_post_array as $keyval) {
$keyval = explode ('=', $keyval);
if (count($keyval) == 2)
$myPost[$keyval[0]] = urldecode($keyval[1]);
}
// read the IPN message sent from PayPal and prepend 'cmd=_notify-validate'
$req = 'cmd=_notify-validate';
if(function_exists('get_magic_quotes_gpc')) {
$get_magic_quotes_exists = true;
}
foreach ($myPost as $key => $value) {
if($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1) {
$value = urlencode(stripslashes($value));
} else {
$value = urlencode($value);
}
$req .= "&$key=$value";
}
$ch = curl_init("https://www.paypal.com/cgi-bin/webscr");
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_FORBID_REUSE, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: Close'));
if(!($res = curl_exec($ch)) ) {
error_log("Got " . curl_error($ch) . " when processing IPN data");
curl_close($ch);
exit;
}
curl_close($ch);
log($res);
I'm on Ubuntu 14.04, with openssl, curl and phpcurl installed, and four hours of debugging.

Finally found the fix for this after speaking with PayPal Technical Support. It was an issue with something they have changed and are working to fix but to get it to work again you simply have to send a "User-Agent" HTTP Header with the Curl request, so something like:
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: Close', 'User-Agent: company-name'));
As for what the "User-Agent" should be set as, it just needs to be at least 5 characters, probably your company name as the example shows but it doesn't have to be.
The Technical Support agent also pointed me to: https://ppmts.custhelp.com/app/answers/detail/a_id/92 if the above fix does not work, but it did for me.

I was also getting access denied (403) from accessing any paypal account, using any browser. Once it happens it continues to happen.
For both Firefox and Safari the solution is to search for all cookies associated with PayPal and delete them. Problem disappears.
