I have developed a small server-client (server: python client: c#) application running on localhost and port 6000. When I start my computer, the client fails to connect to the server on the first attempt. However, if I close and reopen the application, the connection is successful/

def start_server():
    
    host, port = "localhost", 6000
    server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
    server_socket.bind((host, port))

    server_socket.listen(1)
    print("nServer is waiting...")
    connection, address = server_socket.accept()
    
  

    return connection

private void ConnectToServer()
  {
    client = new TcpClient();
     try
      {
        client.Connect("127.0.0.1", 6000);
      }
      catch (Exception ex)
      {
             
       MessageBox.Show("Connection Error: " + ex.Message);
       }
        }
