Ssl 贝宝IPN Listner

一个多星期以来，我一直在努力使它发挥作用。我甚至为该域购买了SSL证书

我不断得到错误： [2016-03-14 18:07欧洲/伦敦]无法连接到PayPal以验证IPN消息：SSL连接错误

这是我的密码

我不知道你为什么要购买SSL证书来修复与PayPal的连接

试着改变

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);

到

我打赌SSL握手在服务器上失败。禁用这些检查将有助于清除问题。

谢谢，尝试过，但仍然出现错误：SSL连接错误这让我非常恼火……这一定是有原因的？？？嗯，尝试添加
curl\u setopt（$ch，CURLOPT\u SSLVERSION，6）到你的网站，你是明星！！谢谢，终于成功了。这只花了一周的时间。我发布了一个更完整的（切中要害的）答案，解释了为什么你必须在“谢谢”上更改这个，尝试了那个，但仍然出现了错误：SSL连接错误这让我很恼火……这一定是有原因的？？？嗯，尝试添加
