I am trying to get local multiplayer in my game. I have setup everything and everything is working fine when I run the game on the same pc (multiple instances) but when I export it to order pc it doesn't connect at all .I have connecting the pc/laptop to same network as LAN. But it doesn't work it only works when I run the instances on the same pc. Any help would be appreciated. I followed this tutorial https://youtu.be/oUPlKYlb27Y

我正在努力让本地的多人参与我的游戏。我已经设置了一切，当我在同一台PC(多个实例)上运行游戏时，一切都运行得很好，但当我将其导出到订购PC时，它根本无法连接。我将PC/笔记本连接到与局域网相同的网络。但它不起作用，只有当我在同一台PC上运行实例时才能起作用。任何帮助都将不胜感激。我遵循了这个教程https://youtu.be/oUPlKYlb27Y

The result should be can connect from other pc

结果应该是可以从其他PC连接
