Mosquitto broker node messages

Hello all
I have setup MQTT settings on my meshatic device using serial and the cli. Set topic and encryption to 0. I have subscribed to the topic on my mosquitto broker but am not seeing any messages passed on the broker terminal. Btw I have tested the broker terminal with the _pub and _ sub two terminals and _ sub is showing messages. Please forgive me I know this is a vague explanation of my issue. Maybe someone could point me to a step by step on setting up your own MQTT broker and testing with meshtastic.
Thanks in advance
