Running my jar in my web server

Networking & Multiplayer

So I have made a Server with Kryonet. I also made a client. They connect fine over local host and all, but now that I have tried to move the server to my web server and run it from there it doesn’t seem to work. I changed localhost to the servers IP and I’m using the port 27960 for TCP and UDP.

Here is how I execute my jar on the server:


<?php
exec("java -jar /JARPATH/jar.jar", $output);
echo $output;
?/>

Warning I don’t have much knowledge of PHP.

And here is my Server code:


static Server server;
	static int tcp = 27960, udp = 27960;
	
	public static void main(String[] args) {
		try {
			server = new Server();
			server.start();
			server.bind(tcp, udp);
		} catch (IOException e) {
			e.printStackTrace();
		}
		
		server.addListener(new Listener() {
			public void connected(Connection c) {
				System.out.println("Succesful client connection");
			}
			
			public void received(Connection c, Object p) {
				
			}
			
			public void disconnected(Connection c) {
				System.out.println("Succesful client disconnection");
			}
		});
	}

And my client code:


public static Client client;
	static String ip = "206.188.193.122";
	static int tcp = 27960, udp = 27960;

        public static void main(String[] args) {
		try {
			client = new Client();
			client.start();
			client.connect(5000, ip, tcp, udp);
		} catch (IOException e1) {
			e1.printStackTrace();
		}
}

What could’ve went wrong here? I know the client connects. It’s got to be something with the IP and port I used. Though I don’t know any other ways I could go about doing this. Can you help?
