老师，我在用阿里云服务器对接我的微信订阅号，服务器是lamp环境，域名是我用来练习的域名charles666.xyz，已备案，可以正常访问。
在微信公众号后台-基本配置-服务器配置时，将服务器和微信公众号对接，注释掉上面代码中的“
$wechatObj->responseMsg()
”，解除下面这个方法调用的注释，
$wechatObj->valid()
提示“提交成功”，已经将服务器配置好了。接下来解除
$wechatObj->responseMsg()
的注释，并注释掉下面这个方法的调用，
$wechatObj->valid()
这时候我在公众号中输入任意文字时，公众号应该弹出“我是你爸爸”的回复消息，但实际上提示的是“该公众号提供的服务出现故障，请稍后再试”。
想问下老师，这个故障怎么解决？我哪一步写错了？
