AB BLE Gateway v4.0 is not showing in MQTT


I have connected the AB BLE Gateway v4.0 via ethernet cable to the router and power as suggested in the Main Page, Gateway Configure Tool V1.2.3 for Linux/Ubuntu has been installed. Setup of the Gateway has been made according Main Page, How To Test.
All lights on the Gateway is flashing as expected.
MQTT Broker has been installed, however, the Gateway is not showing up in MQTT.

Could I please ask you to give me a reason how that can be when everything has been done according to your instructions?
