I try to send/receive data via MQTTPUB and MQTTSUB with mqtt example file in Activate

MQTT broker that I use is mosquitto broker

When I run example to publish and subscribe data, then the error will occur that "Connection Refused: identifier rejected".

On Broker say that "Bad socket read/write on client MQTTPUB: Invalid arguments provided."
