SignalR refusing connections

I'm trying to configure my signalR demo to my project

framework : 4.0 , SignalR version : 1.1.3

Here's my code

$(function () {
            var connection = $.hubConnection('http://localhost:32555/');
            var chat = connection.createHubProxy('myChatHub');
            chat.on('send', function (message) {
                $('#chat').html($('#chat').html() + "\r\n" + message);
            });
            connection.logging = true;
            connection.start().done(function () {
                alert("Connection Complete");
                $('#sendBtn').click(function () {
                    chat.invoke('send', $('#message').val());
                });
            }).fail(function (param) {
                console.log(param);
            });
        });

Global.asax

 protected void Application_Start(object sender, EventArgs e)
        {

            RouteTable.Routes.MapHubs(new HubConfiguration { EnableCrossDomain = true });
        }

.Cs

namespace vPortal
{
    [HubName("myChatHub")]
    public class LetsChat : Hub
    {
        public void send(string message,string userid,string Name)
        {
            Clients.All.addMessage(message, userid, Name);
        }
    }
}

When I tried to run the page I got this error

SignalR: Error during negotiation request:

But, I have enabled proxy in the global.asax I have tried upgrading my signalR to version 2.2.3. But, my project packages are incompatible with the current version so I installed version 1.1.3.

I don't know what I'm doing wrong here I see there is a connection but can not establish.

A lots of credit goes to this man. he made my problem easy to solve.

See, first of all my all the references were to 4.0 then So I used Signalr Older version 1.1.4

Here's is my errors scenario:

  1. SignalR could not connect: I removed this error by adding the lines RouteTable.Routes.MapHubs(); in my Global.asax file.

  2. Negotiation of request: There was a silly mistake done by me the namespace was different in the my chat.aspx page.

  3. Version Conflicts: See, I got previous libraries which were incompatible with the current version (2.3.2) of signalR. So, I had to stick to previous version of it (1.1.3) the steps are given here and its pretty neat.

Again,I was pretty sure about my code signalR will work fine:

So, run my chat and my first message was succeed then Again there was an error after sometime and the error was

the added or subtracted value results in an un-representable datetime. signlar

So, this was the big headache for me.This is definately nothing do with the signalR I got the clue from frebin and I realized that in my web.config 

 <httpRuntime executionTimeout="180" maxRequestLength="512000" />

The executionTimeout previous value was 9999999999

i changed to 180 and its works fine!!!

I have added all the scenarios for the future preferences.
