Why can I connect to the socket but when i emit the authentication data i get no response back

Does anyone know? I am using Java socket.client-io to connect to the websocket, i manage to connect, i get the init event message, but when i try to send authentication data, i get nothing in return. I've checked what i emit from my client with the client provided in the documentation and the emit seems to send the correct data, however i don't get a response back. What could cause this? Am i missing something? :(((((((((((((((((((
