Java Server, PHP client

The Java Server is up and running. It is on one of my open ports (set on my router). It is also not blocked by the firewall (it is white listed). This happens if it is on the webpage : The PHP client just times out and does not successfully connect to the server. I see this message after 30 seconds : "Connection timed out". If I run it in BASH (Linux command line), it works :

It's at least working on the desktop, so I assume it has something to do with PHP and not Java at all. I could be wrong, so I will leave this up for the time being.

Server.java

import java.net.*;
import java.io.*;
 
public class Server {
    public static void main(String[] args) throws IOException {
 
        ServerSocket serverSocket = null;
        try {
            serverSocket = new ServerSocket(****);
        } catch (IOException e) {
            System.err.println("Could not listen on port: ****.");
            System.exit(1);
        }
 
        Socket clientSocket = null;
        try {
            clientSocket = serverSocket.accept();
            System.out.println("Got something");
        } catch (IOException e) {
            System.err.println("Accept failed.");
            System.exit(1);
        }
 
        PrintWriter out = new PrintWriter(clientSocket.getOutputStream(), true);
        BufferedReader in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
        String inputLine, outputLine;
 
        while ((inputLine = in.readLine()) != null) {
        System.out.println(inputLine);
        }
        out.close();
        in.close();
        clientSocket.close();
        serverSocket.close();
    }
}

If you guys could know PHP, please look for the disconnect between the programs :

I also tried the following :

It worked 100% on the desktop, but timed out on the server.

There was absolutely nothing wrong with the code. It was because of the hosting service I was using. I set up an Apache server on my computer and it work 100% now.
