The problem is that I cannot connect to the server socket on the hero.

public static void main(String[] args) { try { int port = Integer.parseInt(System.getenv("PORT")); ServerSocket serverSocket = new ServerSocket(port); System.out.println("Server running " + serverSocket.getLocalPort() + " port..."); //куча весёлого кода } }

Connecting with

 Socket socket = new Socket(ip, port);

I get

 java.net.ConnectException: Connection timed out (Connection timed out)

The server can connect to itself without problems, but from the outside there are already problems. How to fix? Is it even possible for a hero to connect to server sockets?

The code should have a string (and possibly in an infinite loop):

 Socket socket = serverSocket.accept();
