websocket-sharp with pro-presenter stagedisplay

Question

I am trying to use websocket-sharp to interface with a pro-presenter instance as a windows form app. I was able to get a similar project working with JavaScript. My .net version connects to the socket and runs the OnOpen event then immediately runs the OnClose event. Below is my code block. The e.Reason inside the OnClose event is blank. Where am I going wrong?

    using (WebSocket ws = new WebSocket("ws://" + config.ComputerIP + ":" + config.Port + "/stagedisplay"))
    {
        ws.OnOpen += (sender, e) =>
        {
            // send connect string
            ws.Send("{\"pwd\":\"" + config.Password + "\",\"ptl\":610,\"acn\":\"ath\"}");
        };
        ws.OnMessage += (sender, e) =>
        {
                slide.ProcessMessage(e.Data);
                CurrentSlideLbl.Text = slide.CurrentSlide;
        };
        ws.OnClose += (sender, e) =>
            CurrentSlideLbl.Text = "reason:" + e.Reason;

        ws.OnError += (sender, e) =>
            CurrentSlideLbl.Text = "Socket encountered error: Closing socket" + e.Message;

        ws.Connect();
    }

After a lot of troubleshooting I figured it out. It was the way I was trying to open the connection.

        WebSocket ws = new WebSocket("ws://" + config.ComputerIP + ":" + config.Port + "/stagedisplay");
        ws.OnMessage += (sender, e) =>
        {
            slide.ProcessMessage(e.Data);
            CurrentSlideLbl.Invoke(new Action(() => CurrentSlideLbl.Text = slide.CurrentSlide));
        };
        ws.OnOpen += (sender, e) =>
        {
            // send connect string
            ws.Send(JsonConvert.SerializeObject(new { pwd = config.Password, ptl = 610, acn = "ath" }));
        };
        ws.OnClose += (sender, e) => 
        {
            CurrentSlideLbl.Text = "reason:" + e.Reason;
        };

        ws.OnError += (sender, e) => 
        {
            CurrentSlideLbl.Text = "Socket encountered error: Closing socket" + e.Message;
        };

        ws.Connect();
