Hello everyone, I'm a new guy and trying to get familiar with Beckhoff. I'm doing the communication test between CX7080 and the MQTT broker (using Mosquitto). I'm using the twincat in "Oracle Virtual box". 

The architechutre in the below:

First, I already installed the MQTT Mosquitto and configured it. The MQTT is already running

I also did the initial test and it's working

I did the test between the MQTT broker and Local IPC (my laptop) and it's also working

But when I changed to the CX7080, it's not working

Could everyone know the issue and help me?
