  I am working on project of Ionic with angular and AspNet with SignalR that have chat module. I use SignalR for Chat.It's working smoothly but some time i am getting error as per below screen shot and because of that it's get stop working at all. I have hosted my service on IIS and creating proxy and communicating with client and server. Here is sample

  (function () {
          angular
            .module('app')
            .factory('SignalRFactory', SignalRFactory);
          SignalRFactory.$inject = ['$rootScope', 'Hub', 'ionicToast'];
          function SignalRFactory($rootScope, Hub, ionicToast) {
              var signalRLocal = this;
  
              var serverURL = 'URL/signalr';
  
              //Hub setup
              var hub = new Hub('CommunicationHub', {
                  rootPath: serverURL,
                  listeners: {
                      'send': function (data) {
                          console.log("send " + data);
  
                      }
  
                  },
  
  
                  errorHandler: function (error) {
                  //Here i am getting that websocket closed error
                      console.error(error); 
  
                  }
              });
  
  
              signalRLocal.Connect = function (user) {
                  console.log("SignalR Connecting as :" + user.UserName);
                  hub.invoke('connect', user);
              };
  
  
              return signalRLocal;
          }
      })();

  I have hosted service on IIS.

  I also try with  "long Polling" as per below

  Hub.connection.start({ transport: 'longPolling' });

  But i don't want to use "long Polling" at all. So can someone help me to figure out this issue without use of 'long Polling'. Can someone tell me what configuration i have to do at client side or at IIS level.
