Problem in publishing GPS data using Node Red application from Multitech Conduit

I am trying to establish the communication between GPS device and multitech lora gateway server using node red application and below is the screenshot for the same,

and I have setup the MQTT configuration i.e., IP Adress , Port No & QoS

and I have selected the LoRa Mode as a network server in the Multitech Conduit. I am unable to receive the messages on the subscriber side. Is there any step I am missing here? Can anyone please help me to set up this?
