C# TcpListener没有'；无法检测连接

这几天我一直在做客户机-服务器应用程序。我根据示例制作了一个服务器部件来启动TcpListener，它似乎工作得很好。 但是，它无法检测客户端连接，而客户端表示它已连接到给定的ip和端口

以下是我的服务器端代码：

    internal static void RunServer()
    {
        // Create a TCP/IP (IPv4) socket and listen for incoming connections.
        ServerLogger.LogStatus("Starting listener...");
        listener = new TcpListener(IPAddress.Any, Server.PORT + 2);
        listener.Start();
        ServerLogger.LogStatus("Starting thread listener...");
        tlisten = new Thread(Listen);
        tlisten.Start();
        ServerLogger.LogStatus("Starting receiver...");
        treceiver = new Thread(Receiver);
        treceiver.Start();
        ServerLogger.LogStatus("All done!");
    }

    internal static void Listen()  // Listen to incoming connections.
    { 
       while (running)
        {
            ServerLogger.LogStatus("Waiting for a connecion....");
            TcpClient tcpClient = listener.AcceptTcpClient();
            // The below code never runs on client connection.
            ServerLogger.LogStatus("Accepting and Creating cert!");
            // Create a new certification
            byte[] serverCertificatebyte = Certificate.CreateSelfSignCertificatePfx("Test" + IP + RandomString(5),
                new DateTime(2015, 12, 26),
                new DateTime(DateTime.Today.Year, DateTime.Today.Month + 1, DateTime.Today.Day), RandomString(20));
            ServerLogger.LogStatus("Created certificate!");
            X509Certificate serverCertificate = new X509Certificate(serverCertificatebyte);
            tcpclientbytecerts[tcpClient] = serverCertificatebyte;
            tcpclientcerts[tcpClient] = serverCertificate;
            ServerLogger.LogInfo("Sending Certificate!");
            // Send SSL certification in bytes
            tcpClient.GetStream().Write(serverCertificatebyte, 0, serverCertificatebyte.Length);
            ServerLogger.LogInfo("Certificate sent to the client!");
            Logger.Log(serverCertificatebyte.ToString());
            // process it
            ServerLogger.LogInfo("Processing");
            ProcessClient(tcpClient, serverCertificate);
            ServerLogger.LogInfo("Processed!");
        }
    }

客户端：

    private SSL(string ip, int port)
    {
        UnityEngine.Debug.Log("Test");
        if (!PrivacyHelper.IsInvocationAllowed())
        {
            Terminate();
        }
        UnityEngine.Debug.Log("Test2 " + ip + " - " + port);
        UnityEngine.Debug.Log("Test3 " + IsLocalIpAddress(ip));
        client = new TcpClient(ip, port);
        //client.Connect(ip, port);
        UnityEngine.Debug.Log("Test4 " + client.Connected); // <- This is true
        var stream = client.GetStream();
        UnityEngine.Debug.Log("Test5");
        Byte[] cert = new Byte[65535];
        UnityEngine.Debug.Log("Test6");
        Int32 bytes = stream.Read(cert, 0, cert.Length);
        UnityEngine.Debug.Log("Test7");
        byte[] intBytes = BitConverter.GetBytes(bytes);
        UnityEngine.Debug.Log("Test8");
        if (BitConverter.IsLittleEndian) { Array.Reverse(intBytes);}
        UnityEngine.Debug.Log("Test9");
        byte[] result = intBytes;
        UnityEngine.Debug.Log("Cert: " + result);
        certificate1 = new X509Certificate2(result);
        //client.GetStream().Read()
    }

私有SSL（字符串ip，int端口）
{
UnityEngine.Debug.Log（“测试”）；
如果（！PrivacyHelper.isInvocationLowed（））
{
终止（）；
}
UnityEngine.Debug.Log（“Test2”+ip+“-”+port）；
UnityEngine.Debug.Log（“Test3”+IsLocalIpAddress（ip））；
客户端=新的TCP客户端（ip、端口）；
//client.Connect（ip，端口）；
UnityEngine.Debug.Log（“Test4”+client.Connected）；//什么是Server.PORT+2？为什么是+2？Server.PORT是游戏服务器的端口。假设28015是端口，28016是查询端口。这就是为什么我做+2在你询问new SSL（）之前，我已经添加了+2。因此它连接到28017端口。
