SignalR event becomes intermittent when deployed to a server

Question

When running locally through VS - IIS Express it all works fine 100%.

When i then publish to a webserver (on network or online) I have some event stop firing for \"O

Answer 1

Not a satisfying fix but adding a thread sleep before ResetTimer() seems to have fixed it.

    Groups.Add(Context.ConnectionId, @group.Name);
    Clients.OthersInGroup(@group.Name).addMessage(HttpUtility.HtmlEncode(user.Name + " has connected."));
    Clients.Caller.addMessage(HttpUtility.HtmlEncode("You've connected..."));

    Thread.Sleep(TimeSpan.FromSeconds(1)); //<<<<<<<<<
    ResetTimer(@group.Name);

Addendum

Even even better fix, issue is Groups.Add is ASYNCHRONOUS!! awaiting it solves the issue also. (dont forget to make OnConnected async too)

    public async override Task OnConnected()
    {
      --->> await Groups.Add(Context.ConnectionId, "TestGroup"); 

            Clients.Group("TestGroup").showBoxOne();
            Clients.Group("TestGroup").showBoxTwo();
            Clients.Group("TestGroup").showBoxThree();
            Clients.Group("TestGroup").showBoxFour();
            Clients.Group("TestGroup").showBoxFive();
        }

        await base.OnConnected();
    }
