1. 先确定网络是不是通的：
   telnet 一下192.168.249.1 1883 和127.0.0.1 1883
   如果是通的。
2. 把emqx的日志调成debug级别，然后重启。连接时看看emqx的日志有什么异常。

能ping通，防火墙已关闭，端口没有占用，为啥同样的ip WebSocket的可以？

[zhongwencool]

用ping没什么用的。要用telnet啊

[872332847]

telnet 没有提示

[zhongwencool]

windows的telnet不会提示的么。我不太清楚。
你telnet 127.0.0.1和192.168.249.1 都是一样的现象么？
你直接对比一下telent18083端口（这个肯定是通的）的现象，如果是一样的。说明就是通的。

如果确定是通的，那上面的第2条看看日志。

[872332847]

127.0.0.1 1883 、192.168.249.1 1883、127.0.0.1 18083 telnet 时都一样，没有提示
127.0.0.1 18083 能打开管理页面

后面改用Docker 镜像，启动 Docker 容器。就能访问了

你好，你这个websocket，是怎么连接上的。我这边正好和你的情况相反，mqtt协议版本3.1.1
