Hi and welcome to the forum.

You didn't say which O/S you are running. But this works if you are on a RasPi or ubuntu.

My local notes below:
You will have to open TWO command lines/terminal sessions.

How to send MQTT messages

-h HOST
-t TOPIC
-m MESSAGE

mosquitto_sub -h 127.0.0.1 -t armtronix_mqtt

mosquitto_pub -h 127.0.0.1 -t armtronix_mqtt -m "Hi this is Armtronix_server"

Show us what you have entered in the MQTT config node settings
