About 3 days we are searching for a solution... local, in IIS Express, everything works fine... after the deploy on Azure Web App, we start facing SignalR going crazy...

We have a WebJob that connects to a hub to send updates in real time...
To validate connection problems, I get a return value from the function called in server, it is all getting there... so, the connections are being made successfuly...

On my hub, after receive the value from the WebJob, i call a Javascript Function on my web app... every user logged in need to receive updates.

But this function never trigger on Azure... Locally it is all working great.

After that, we tried almost everything...

If the request came from the same browser instance, the function were call successfuly.

Check it out here:

Open this link:

Then open this other link to send notification:

http://unique-dev.azurewebsites.net/AdministratorDashboard/SendNotifications?text=mymessage

SignalRClient.js

var uniqueHub;

$(function () {



    uniqueHub = $.connection.billingHubNotification;

    uniqueHub.client.uniqueEngineAlert = function (content) {

        alert(content);

    };



    $.connection.hub.start()

        .done(function () { })

        .fail(function () { console.log('Could not Connect!'); });;



    $.connection.hub.error(function (error) {

        console.log('SignalrAdapter: ' + error);

    });

});

Action in Controller

[HttpGet]

[AllowAnonymous]

public ActionResult SendNotifications(string text)

{

    try

    {

        var hubContext = GlobalHost.ConnectionManager.GetHubContext<BillingHubNotification>();

        var exec = hubContext.Clients.All.uniqueEngineAlert(text);



        return Content("Sucesso");

    }

    catch (Exception ex)

    {

        return Content("Erro: " + ex.Message);



    }

}

Hub

    [HubName("billingHubNotification")]

    public class BillingHubNotification : Hub

    {

        IHubContext _context

        {

            get

            {

                var context = GlobalHost.ConnectionManager.GetHubContext<BillingHubNotification>();

                return context;

            }

        }

        public override Task OnConnected()

        {

            string name = Context.User.Identity.Name;



            _context.Groups.Add(Context.ConnectionId, name);



            return base.OnConnected();

        }





        public void UniqueEngineAlert(string alert, string userNames)

        {

            foreach (var user in userNames)

            {

                _context.Clients.Group(user).uniqueEngineAlert(alert);

            }

        }

    }
