连接到EC2（AWS）上的C＃服务器

Question

I'm trying to connect to a C# TCP server I'm running on EC2. But my server's not responding. This is the code that running on the EC2:

static void Main(string[] args)
{
    TcpListener serverSocket = new TcpListener(8888);
    TcpClient clientSocket = default(TcpClient);
    serverSocket.Start();
    clientSocket = serverSocket.AcceptTcpClient();
    Console.WriteLine("new client connected");
}

And them from my own PC I'm trying to run this code:

static void Main(string[] args)
{
    TcpClient clientSocket = new TcpClient();
    clientSocket.Connect("35.163.41.3", 8888);
    Console.WriteLine("you connected to the server!");
}

This is the security group of my EC2:

What could the problem be?

Answer 1

It could be a number of things. First thing I would check is Windows Firewall on the server to make sure that it is allowing that port.
