Broadcast not received in Client-Unet

Question

I am using unet for client-server communication, when i broadcast a message from server(on PC) to client(on PC) it works fine but when i try the same from server(PC) to client(Hololens emulator) unet doesn't work.

NetClient.cs

public override void OnReceivedBroadcast(string fromAddress, string data)
    {
        fromAddress1 = fromAddress;
        portnum = data;
        Connect_with_server();
    }
 void Connect_with_server()
    {
            myclient = new NetworkClient();
            myclient.RegisterHandler(MsgType.Connect, OnConnected);
            myclient.RegisterHandler(MsgType.Disconnect, OnDisconnected);
            myclient.RegisterHandler(ChatMsg.PlayPauseID, redgreen_val_received);
            myclient.Connect(fromAddress1, Convert.ToInt32(portnum));
    }

Server.cs

void Start()
    {
        startServer();
    }
 public void startServer()
    {
        int serverPort = createServer();
        if (serverPort != -1)
        {
            Debug.Log("Server created on port : " + serverPort);

            discovery.broadcastData = serverPort.ToString();
            discovery.Initialize();
            discovery.StartAsServer();
        }
        else
        {
            Debug.Log("Failed to create Server");
        }
    }


    int minPort = 10000;
    int maxPort = 10010;
    int defaultPort = 10000;
    private int createServer()
    {
        int serverPort = -1;
        bool serverCreated = NetworkServer.Listen(defaultPort);
        if (serverCreated)
        {
            serverPort = defaultPort;
        }
        else
        {
            Debug.Log("Failed to create with the default port");
            for (int tempPort = minPort; tempPort <= maxPort; tempPort++)
            {
                if (tempPort != defaultPort)
                {
                    if (NetworkServer.Listen(tempPort))
                    {
                        serverPort = tempPort;
                        break;
                    }
                    if (tempPort == maxPort)
                    {
                        Debug.LogError("Failed to create server");
                    }
                }
            }
        }
        return serverPort;
    }

    void OnClientConnected(NetworkMessage netMessage)
    {
        MyNetworkMessage messageContainer = new MyNetworkMessage();
        messageContainer.message = "Thanks for joining Mr.Client!";
        Debug.Log("Client connected: ");
    }

PS: I have turned on Private network client-server in UWP capability settings and also turned on PrivateNetworkClientServer and InternetClientServer in Player settings.

The HL2 emulator is Hyper-V virtual machine. Have you enabled external virtual switch on your PC and connected it to the emulator? — Tania Chistyakova, Jul 29 '19 at 12:52

May not be a direct solution to your problem, but when I use network broadcasting from Unity's UNET, HoloLens will often suddenly stop discovering the broadcast for no apparent reason. I simply turn the HoloLens off and on again (long pressing the power button) and the problem resolves.

Please confirm if you can ping the HoloLens emulator from your computer. If it unable to connect, follow the this case to fix the issue: HoloLens emulator connect to server on LAN

Besides, as for the NetworkManagerHUD, to my knowledge does not work on the HoloLens.
