You need to make sure you don't try invoking server-side hub methods until start is done. Ex:

$.connection.hub.start().done(function(){
     $('#submit').click(function () {
         $.connection.chat.server.addMessage($('#msg').val());
     })
});

Notice that the event handler isn't wired up until the connection is established.
