未设置Webhook！错误：400错误的请求：错误的Webhook：无法设置自定义证书文件。
我使用了PHP，Apache 2.4和Amazon Web Services EC2。
嗨，我必须设置Telegram机器人的webhook，但是当我去从php setHook.php终端执行命令时，这就是给我的：
Webhook was not set! Error: 400 Bad Request: bad webhook: Failed to set custom certificate file
所以我尝试查看文件error.log以查看是否可以在其中找到问题：

如何解决此问题并使我的Telegram机器人与Amazon EC2服务器正确对话？
最好的问候， Matteo。
