Correct logic to reconnect in SignalR with HubConnection

To fix this issue So I found this coolest solution Best practice for reconnecting SignalR 2.0 .NET client to server hub
private async Task<bool> ConnectToSignalRServer()
    bool connected = false;
        Connection = new HubConnection("server url");
        Hub = Connection.CreateHubProxy("MyHub");
        await Connection.Start();

        //See @Oran Dennison's comment on @KingOfHypocrites's answer
        if (Connection.State == ConnectionState.Connected)
            connected = true;
            Connection.Closed += Connection_Closed;
        return connected;
    catch (Exception ex)
        return false;

private async void Connection_Closed()
    if(!IsFormClosed) // A global variable being set in "Form_closing" event of Form, check if form not closed explicitly to prevent a possible deadlock.
        // specify a retry duration
        TimeSpan retryDuration = TimeSpan.FromSeconds(30);

        while (DateTime.UtcNow < DateTime.UtcNow.Add(retryDuration))
            bool connected = await ConnectToSignalRServer(UserId);
            if (connected)
        Console.WriteLine("Connection closed")

it should still fix some issue I presume you followed the walkthrough that came with 0.5.3's announcement already? http://blogs.msdn.com/b/webdev/archive/2012/08/22/announcing-the-release-of-signalr-0-5-3.aspx
make sure you can open both /Scripts/jquery.signalR-0.5.3.js and /signalr/hubs in a browser.

This might help you It's not necessary if you are calling Stop().

Does that help If you are using your own custom token you can do like this:
Client(.NET, but i think you will understand):
var connection = new HubConnection("url", "CustomToken=SomeToken");
    public override Task OnConnected()
        if(Context.QueryString["CustomToken"] != "CorrectToken")
            ///Forcefully close the connection
        return base.OnConnected();

may help you . In case anyone else runs into this problem, I'm posting the answer here.
I was able to work around this problem by updating all SignalR and related NUGet packages to their version 3.x pre-release versions.
