I'm seeing lots of entries in my logs from this request:
/signalr/negotiate
The error is:
The controller for path '/Account/Login' was not found or does not implement IController
I have a JS client connecting to an AppHub
that requires authentication:
[Authorize]
[HubName("appHub")]
public class AppHub : Hub
{
// content
}
This is happening because there's an 'signalr` session alive with an expired cookie attempting to connect:
If I understand your issue correctly then you are going to want to create your own custom class to handle this by inheriting the AuthorizeAttribute class: https://msdn.microsoft.com/en-us/library/system.web.mvc.authorizeattribute(v=vs.118).aspx
For example:
public class MyCustAuthorize : AuthorizeAttribute
{
protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
{
if (!filterContext.HttpContext.User.Identity.IsAuthenticated)
{
filterContext.Result = new HttpUnauthorizedResult();
}
else
{
//modify this to do whatever you want to happen if unauthorized
filterContext.Result = new RedirectResult("/session/noaccess/");
}
}
}
Then you can decorate it with your custom class instead of the default authorize (example is from a mvc controller but should be able to function the same on your hub) So this:
[Authorize]
public class AdminController : Controller
{
Becomes this:
[MyCustAuthorize]
public class AdminController : Controller
{
I believe the /Account/Login is the default path for forms auth so that is why it is directing there if it is not defined within your config file.
Alternatively you could insert the specific url to redirect to if that is what you are searching for by placing the following loginUrl attribute value in your auth section > forms element in the web.config:
It looks like this may be similar to these other answers to questions already asked here and these may provide your solution:

Have you tried stopping the connection in the client when they are no longer authorized?
$.connection.hub.stop();
