Broadcast not received in Client-Unet

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

Code (CSharp):

1. public override void OnReceivedBroadcast(string fromAddress, string data)
2.    {
3.        fromAddress1 = fromAddress;
4.        portnum = data;
5.        Connect_with_server();
6.    }
7. void Connect_with_server()
8.    {
9.            myclient = new NetworkClient();
10.            myclient.RegisterHandler(MsgType.Connect, OnConnected);
11.            myclient.RegisterHandler(MsgType.Disconnect, OnDisconnected);
12.            myclient.RegisterHandler(ChatMsg.PlayPauseID, redgreen_val_received);
13.            myclient.Connect(fromAddress1, Convert.ToInt32(portnum));
14.    }

Server.cs

Code (CSharp):

1. void Start()
2.     {
3.         startServer();
4.     }
5. public void startServer()
6.     {
7.         int serverPort = createServer();
8.         if (serverPort != -1)
9.         {
10.             Debug.Log("Server created on port : " + serverPort);
11.  
12.             discovery.broadcastData = serverPort.ToString();
13.             discovery.Initialize();
14.             discovery.StartAsServer();
15.         }
16.         else
17.         {
18.             Debug.Log("Failed to create Server");
19.         }
20.     }
21.  
22.  
23.     int minPort = 10000;
24.     int maxPort = 10010;
25.     int defaultPort = 10000;
26.     private int createServer()
27.     {
28.         int serverPort = -1;
29.         bool serverCreated = NetworkServer.Listen(defaultPort);
30.         if (serverCreated)
31.         {
32.             serverPort = defaultPort;
33.         }
34.         else
35.         {
36.             Debug.Log("Failed to create with the default port");
37.             for (int tempPort = minPort; tempPort <= maxPort; tempPort++)
38.             {
39.                 if (tempPort != defaultPort)
40.                 {
41.                     if (NetworkServer.Listen(tempPort))
42.                     {
43.                         serverPort = tempPort;
44.                         break;
45.                     }
46.                     if (tempPort == maxPort)
47.                     {
48.                         Debug.LogError("Failed to create server");
49.                     }
50.                 }
51.             }
52.         }
53.         return serverPort;
54.     }
55.  
56.     void OnClientConnected(NetworkMessage netMessage)
57.     {
58.         MyNetworkMessage messageContainer = new MyNetworkMessage();
59.         messageContainer.message = "Thanks for joining Mr.Client!";
60.         Debug.Log("Client connected: ");
61.     }

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