Non UTF-8 messages will throw exception

[znjp]

If a connected client sends non-UTF8 data, run() will throw an uncaught exception. I added a try/except to catch it, but maybe better options?

                    try:
                        connected_node_id   = connection.recv(4096).decode('utf-8')
                    except Exception as e:
                        print(e)
                        connection.close()
                        continue
