Hi, I use WebBrowserInput demo on LAN, WebSocket, everything else by default. I opened it in the browser and could see the Unity camera's real-time content and interactively control the lighting. When I mapped the machine to a WAN address, I could open a web page on another machine using a browser on the WAN and see buttons and a gray background. But clicking the button does not work, and you cannot see the video. How should I modify it? Thank you very much!
