I have been working with SignalR for real time communication in my application for a quite long time but for past few days, I have been facing a strange issue,i.e. After working fine for sometime, signalR seems to be stuck in a way that its showing connected, getting new connection ID on every attempt but not invoking the messages, either used from a JS client or from a Windows/Web Client.

Any Idea/help will be really appreciated?

What I have tried:

Tried google, MSDN, SO and ASP.NET Articles related to SignalR.

var chat = $.connection.myHUB; $.connection.hub.start().done(function () { var groups = []; chat.server.subscribe('@User.Identity.Name', groups); //After this line it shows no response. });

What about your Hub (Server code)? And the startup configuration? If you can debug your server method "subscribe", would you be able to put a breakpoint in it and check if the server method is actually called after "chat.server.subscribe('@User.Identity.Name', groups);" ?

It works fine when the SignalR server is started after an IIS Reset(using iisreset command via cmd), and it continue to work fine for quite sometime, But suddenly it stops communicating with the server and didnt hit the breakpoint either.

I have been able to reproduce the scenario by doing as below. 1-Build the application(having SignalR Server i.e. HUB) 2-Start the application, It works fine. 3- Stop or Restart the IIS. 4- SignalR client will seems to be reconnected and getting new connection id every time after the step 3. 5-But didnt reach the SignalR Server.
