However none of these events are being fired. I took it a step further and put logging on all the events I could yet none of them are being called the connection drops.

Try to use the following code, I test it on my side, it seems that the disconnected event works well on my side:

Thank you for your quick response, I already tried that method and I even tried that exact code and its not triggering when I stop the app pool for example. Could something be conflicting with just these events? When its connected everything works great.

How to notify the user about disconnections?
Jun 15, 2017 09:44 PM|jakeb16|LINK
I need some help figuring out how to let our users know the connection is disconnected. I'm using the latest version 2.2.2
I read this https://docs.microsoft.com/en-us/aspnet/signalr/overview/guide-to-the-api/handling-connection-lifetime-events#notifydisconnect
However none of these events are being fired. I took it a step further and put logging on all the events I could yet none of them are being called the connection drops.
$.connection.hub.connectionSlow = RealTimeInboxConnectionSlow;
$.connection.hub.reconnecting = RealTimeInboxReconnecting;
$.connection.hub.reconnected = RealTimeInboxReconnected;
$.connection.hub.disconnected = RealTimeInboxDisconnected;
$.connection.hub.stateChanged = function () { RealTimeInboxSignalRConsoleLog("StateChange"); };
$.connection.hub.error(function (error) { RealTimeInboxSignalRConsoleLog('Error: ' + error) });
$.connection.hub.received(function (data) { RealTimeInboxSignalRConsoleLog('Received: ' +JSON.stringify(data)) });
$.connection.hub.logging = true;
This is What I see in the browser console when the app pool is stopped is a loop of trying to reconnect
14:36:16 GMT-0700 (US Mountain Standard Time)] SignalR: EventSource readyState: 0.
[14:36:16 GMT-0700 (US Mountain Standard Time)] SignalR: EventSource reconnecting due to the server connection ending.
[14:36:18 GMT-0700 (US Mountain Standard Time)] SignalR: EventSource calling close().
[14:36:18 GMT-0700 (US Mountain Standard Time)] SignalR: serverSentEvents reconnecting.
14:36:18 GMT-0700 (US Mountain Standard Time)] SignalR: Attempting to connect to SSE endpoint
[14:36:18 GMT-0700 (US Mountain Standard Time)] SignalR: EventSource readyState: 2.
[14:36:18 GMT-0700 (US Mountain Standard Time)] SignalR: EventSource reconnecting due to the server connection ending.
[14:36:20 GMT-0700 (US Mountain Standard Time)] SignalR: EventSource calling close().
Over and Over again.
I reported this as a issue on github but I dont see how I can be the only one facing this problem.
Any one have any suggustions?
I am using SSE, forever frames, and long polling (we dont have the newer version of Windows so we cant use winsockets)

Hi jakeb16,
Try to use the following code, I test it on my side, it seems that the disconnected event works well on my side:
$.connection.hub.disconnected(function () { alert("disconnected"); });Best regards,

A co-worker finally pointed me to the problem I was overriding the handlers instead of passing my function to them
$.connection.hub.disconnected = RealTimeInboxDisconnected;
vs
$.connection.hub.disconnected( RealTimeInboxDisconnected);
