WebSocket server refusing connections.

Hi,
Thanks to this lab, I wanted to test a simple websocket chat server.
Everything works fine on IIS Express and IIS on my local machine.
But once the site published, I can't connect to endpoint through any way (Javascript websocket or native WebSocket c#).
Is there any restrictions on this ?

Here is my Handler:

Code:

    public class WSHandler : IHttpHandler
    {
 
        public void ProcessRequest(HttpContext context)
        {
            if (context.IsWebSocketRequest)
            {
                try
                {
                    context.AcceptWebSocketRequest(ProcessWSChat);
                }
                catch(Exception e)
                {
                    context.Response.StatusCode = 400;
                }
            }
            else
                context.Response.StatusCode = 400;
        }
 
        public bool IsReusable { get { return false; } }
 
        List<WebSocket> socketList = new List<WebSocket>();
 
        private async Task ProcessWSChat(AspNetWebSocketContext context)
        {
            WebSocket socket = context.WebSocket;
            socketList.Add(socket);
            try
            {
                while (true)
                {
                    ArraySegment<byte> buffer = new ArraySegment<byte>(new byte[1024]);
                    WebSocketReceiveResult result = await socket.ReceiveAsync(buffer, CancellationToken.None);
                    if (socket.State == WebSocketState.Open)
                    {
                        if (result.MessageType == WebSocketMessageType.Text && result.EndOfMessage)
                        {
 
                            string userMessage = Encoding.UTF8.GetString(buffer.Array, 0, result.Count);
                            buffer = new ArraySegment<byte>(Encoding.UTF8.GetBytes(userMessage));
                            Parallel.ForEach(socketList, (s) => s.SendAsync(buffer, WebSocketMessageType.Text, true, CancellationToken.None));
                        }
                    }
                    else
                    {
                        break;
                    }
                }
            }
            catch(Exception ex)
            {
 
            }
        }
    }

Thanks,

Hi,
Thanks for your reply.
Regarding the requirements, this is ok as I'm beta testing Windows 2012/IIS8 environment.
Regarding the support, I need an account and I have only the labs account :-(
