I have hosted my service on IIS and creating proxy and communicating with client and server. Here is sample

            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;
            }
        })();


    Error: WebSocket closed.

    was interrupted while the page was loading.

    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.
