It seems that your client closes the connection after one message.

responseData = System.Text.Encoding.ASCII.GetString(data, 0, bytes);
client.Close();
return responseData; //returns what server writes

If you want to persist the connection you should have a loop on the client similar to the one you have on the server. If you want to establish a new connection every time you should close the stream gracefully on the server and not have a loop like this. You will still need to loop in case the message is longer or you need to specify max length for the command.
