> MQTT spec says:
> [MQTT-3.1.2-2]
> The Server MUST respond to the CONNECT Packet with a CONNACK return code 0x01 (unacceptable protocol level) and then disconnect the Client if the Protocol Level is not supported by the Server.
> [MQTT-3.2.2-5]
> If a server sends a CONNACK packet containing a non-zero return code it MUST then close the Network Connection.
