title: Websocket server connection
body: <p>I want to make a server with websocket. I've tried a lot of programming language (python, php, c++, etc.), and everything seems okay as far as I connect to it as ws://127.0.0.1:12345. But if I try to change the address to the IP of my PC (89.135.123.456), then I can't connect to the server. The server is always binded to the IP 0.0.0.0, the port 12345 is enabled in my router. I can connect to the xampp server by using my IP adress. What's the reason I can't connect to it with my IP adress?</p>
