使用 acme 疑似遇到 bug 请教

执行命令：
`acme.sh --issue -d xxx.top --standalone --httpport 9500 --debug`

部分 debug 输出：
```

此日志是否表明了它还在致力于连接 80 端口，我的 httpport 参数指令似乎无法生效？

补充以下
根据文档描述。

你可以使用 --standalone --httpport 88 在没有 nginx 等前置代理时将 80 端口请求转发到 88 端口

例如你写了各 http 服务，监听在 9500 端口，同时你也没有开 nginx 等，或者 nginx 根本没有配置你要申请证书的域名，且你的 80 端口没有没占用，防火墙也都顺畅，你也不想麻烦配置 nginx 等，那么你就

--standalone --httpport 9500 搞起来，

@LLaMA2 这个用法是不对的，我本身也验证过了，我的日志就是该错误用法的示范输出。
一楼老哥的说法就是正确的。

我后来回去琢磨了一下官方文档为什么加了 httpport 无法起作用，其实官方的意思是：你的最外层拥有一个负载均衡器，它是监听的 80 端口的，然后比如你把负载均衡器的 80 端口绑定到某台内网机器的 9500 端口了，这时候你才需要去加 --httpport 9500 来使用。

官方文档描述的使用场景的文案，其实不那么好理解，容易造成误解。
