Push realtime data on web page using signalr

I have recently heard about signalR. I want to display Realtime data on web application. I have a console application in asp.net which receives Realtime data from a device and sends on udp port. This udp data sent by console application should be displayed in web browsers in Realtime. After exploring on internet I found a project on this forum only which displays server system time on web page. But I want to modify it to receive my Udp data from console application. After modification of ClockHub.cs I get error " System.Net.Sockets.SocketException: 'Only one usage of each socket address (protocol/network address/port) is normally permitted'  Please suggest a solution so that I may display the data received from console application on web page of a web application

Client.js
<pre lang="Javascript">var countryZone = "Bangladesh Standard Time";
$(document).ready(function () {
    var hubProxy = $.connection.clockHub;
    hubProxy.client.setTime = function (time) {
        $('#clock').html(time);
    };
    $.connection.hub.start().done(function () {
        setInterval(function () {
            hubProxy.server.getTime(countryZone);
        }, 1000);
    });
});
function select_country() {
    countryZone = $("#lstCountry").val();
}

namespace RealTimeClock.App_Code
{
    public class ClockHub : Hub
    {
        public void getTime(string countryZone)
        {
           // TimeZone currentZone = TimeZone.CurrentTimeZone;
          //  DateTime currentDate = DateTime.Now;
           // DateTime currentUTC = currentZone.ToUniversalTime(currentDate);
           // TimeZoneInfo selectedTimeZone = TimeZoneInfo.FindSystemTimeZoneById(countryZone);
           // DateTime currentDateTime = TimeZoneInfo.ConvertTimeFromUtc(currentUTC, selectedTimeZone);
             //My modified code to receive udp data from console application
UdpClient receivingUdpClient = new UdpClient(11000); 
IPEndPoint RemoteIpEndPoint = new IPEndPoint(IPAddress.Any, 0);
Byte[] receiveBytes = receivingUdpClient.Receive(ref RemoteIpEndPoint);
string returnData = Encoding.ASCII.GetString(receiveBytes);            
         Clients.Caller.setTime(returnData );
        }
    }
