P2P testing problems

[0xddy]

MyServer Url http://demo.lmcw.cn

My Tracker Server ws(s)://tracker.lmcw.cn

✅With the same computer and different browsers

❌Different devices, the same LAN network （ It just happened in my own life ，Using GitHub demo （http://novage.com.ua/p2p-media-loader/demo.html） is good）

What is the cause of this？
