PayPal IPN отказ SSLv3 оповещения рукопожатие

Question

После использования sample IPN script от PayPal для обработки входящих платежей:

<?php 

// CONFIG: Enable debug mode. This means we'll log requests into 'ipn.log' in the same directory. 
// Especially useful if you encounter network errors or other intermittent problems with IPN (validation). 
// Set this to 0 once you go live or don't require logging. 
define("DEBUG", 1); 

// Set to 0 once you're ready to go live 
define("USE_SANDBOX", 1); 


define("LOG_FILE", "./ipn.log"); 


// Read POST data 
// reading posted data directly from $_POST causes serialization 
// issues with array data in POST. Reading raw POST data from input stream instead. 
$raw_post_data = file_get_contents('php://input'); 
$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 post from PayPal system and add 'cmd' 
$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"; 
} 

// Post IPN data back to PayPal to validate the IPN data is genuine 
// Without this step anyone can fake IPN data 

if(USE_SANDBOX == true) {

Журнал показывает все время:

[2016-03-17 19:08 Europe/Berlin] Can't connect to PayPal to validate IPN message: error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure 

Выполнение некоторых поиска приводит к большому количеству проблем, связанных с этим сообщение об ошибке, я попытался сменить:

• CURLOPT_SSLVERSION 4

• CURLOPT_SSL_CIPHER_LIST в TLSv1

все это не решает мою проблему. Ошибка все тот же. Я работаю над настройкой своего локального разработчика.
