i tried echoing the messages back to me and it work perfectly. Now i moved on creating a chat server that adds a new client to the chat group and broadcast any incoming messages to all connected clients , i have configure and installed everything but the Group() doesn't work and nothing is happing and no error have been shown so i don't know where is the problem?
