Question

概述
最近，这个问题严重地杀了我。我正在尝试通过服务器和客户端通过网络建立连接。在显示代码之前，我想说一下我已经搜索了多个线程来解决此问题，但是这让我很疯狂。

错误：连接尝试失败是因为一段时间后被连接方未正确响应，或者是由于连接的主机未能响应而导致建立连接失败。

从这里开始的事情是我尝试过的事情的列表：
  端口转发
  -使用本地IP和LAN IP（即127.0.0.1、192.168.1.4、10.0.0.150），这些IP将起作用并将我连接到服务器，而我的外部IP无法使用。
  -经过检查的防火墙
  -尝试使用其他端口，以防ISP阻止特定端口（25567、28567等）

现在输入我的代码...

客户端Unity3D：

public string host = "Insert IP Here";
public int port = 25567;
public TcpClient socket = new TcpClient();
public void ConnectToServer()
{
    while (true)
    {
        try
        {
            socket.ReceiveTimeout = 100;
            socket.SendTimeout = 100;
            socket.Connect(new IPEndPoint(IPAddress.Parse(host), port));
            stream = socket.GetStream();
            writer = new StreamWriter(stream);
            reader = new StreamReader(stream);
            MasterCommunication MC = GameObject.Find("Main").GetComponent<MasterCommunication>();
            MC.setCommunicationPrams(socket, stream, reader, writer, true);
            socketReady = true;
            break;
        }
        catch (Exception e)
        {
            Debug.Log("Connection timed out.");
            Debug.Log(e.Message);
            break;
        }
    }
}

服务器（Visual Studio）：

        public static int port = 63292;
    private static TcpListener server;
    static void Main(string[] args) // Main Method
    {
        #region Initialization
        Console.WriteLine("...Server Initializing");
        clients = new List<ServerClient>();
        disconnectList = new List<ServerClient>();
        try
        {
            IPEndPoint IPEP = new IPEndPoint(IPAddress.Any, port);
            Console.WriteLine("...IPEP set to " + IPEP.AddressFamily);
            Console.WriteLine("...Port Set to " + port);
            server = new TcpListener(IPEP);
            server.Start();
            StartListening();
            Thread dataListener = new Thread(ListenForData);
            dataListener.Start();
            if (Directory.Exists(Directory.GetCurrentDirectory() + "/Database"))
            {
                Console.WriteLine("...Database Found");
            }
            else
            {
                Directory.CreateDirectory(Directory.GetCurrentDirectory() + "/Database");
                Console.WriteLine("...Database Created");
            }
            Database.VerifyDatabase(Directory.GetCurrentDirectory() + "/Database");
            Console.WriteLine("...Server has successfully started.");
        }
        catch (Exception e)
        {
            Console.WriteLine("Socket error: " + e.Message);
        }
        #endregion


    }

服务器（下半部分）

private static void StartListening() => server.BeginAcceptTcpClient(AcceptTcpClient, server);

    private static void AcceptTcpClient(IAsyncResult ar)
    {
        try
        {
            Console.WriteLine("-New Connection");
            TcpListener listener = (TcpListener)ar.AsyncState;
            clients.Add(new ServerClient(listener.EndAcceptTcpClient(ar)));
            StreamWriter writer = new StreamWriter(clients.Last<ServerClient>().tcp.GetStream());
            writer.WriteLine(Encryption.Encrypt("Connected~Connected"));
            writer.Flush();
            StartListening();
        }
        catch (Exception e)
        {
            Console.WriteLine(e.Message);
            StartListening();
        }
    }
