DSGW-200 MQTT Posting

Hi, I have the DSGW-200 device. When I use a location broker like Explore MQTT, I can get the data in the local MQTT. I tried connecting the device to an EMQX cloud server to monitor the data remotely. I tested another device with the EMQX details, and it connects to the broker successfully, but only the DSGW-200 is not connecting to the cloud.

Could you provide guidance on how to connect the DSGW-200 device to EMQX to receive data remotely?
