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 = 'https://serivcerURL.com/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;
}
})();
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.
your socket seems to be getting disconnected because of inactivity, some hosts do that send a dummy heart-bit message every 50 seconds to keep the connection alive

WebSocket requires the server to be using Windows Server 2012 or Windows 8, and .NET Framework 4.5. If these requirements are not met, SignalR will attempt to use other transports to make its connections. Also you need to use latest browsers in order
to support websockets. Check https://docs.microsoft.com/en-us/aspnet/signalr/overview/getting-started/supported-platforms.

I search for the solution and find something like this https://stackoverflow.com/questions/31011288/signalr-2-2-0-websocket-error-connecting-to-hub
I also try with above link solution by using "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.

try reconnecting when disconnected:
$.connection.hub.disconnected(function() { setTimeout(function() { $.connection.hub.start(); }, 5000); // Re-start connection after 5 seconds });Please remember to click "Mark as Answer" the responsES that resolved your issue.

Hi sagarh,
WebSocket requires the server to be using Windows Server 2012 or Windows 8, and .NET Framework 4.5. If these requirements are not met, SignalR will attempt to use other transports to make its connections. Also you need to use latest browsers in order to support websockets.
