Is this at home or in office ?

The logic machine is remote so i am logged in via an ICE remote access to the site. On lowest picture.

But what is the site? is this normal home with single router or some office with managed switch/router?
I'm asking as it sound like you have blocked outgoing port 1883.  Usually this is not blocked but in office environment it can happen.
Do you have any errors in LM?

Big office building yes. And i guess that this is the problem regarding MQTT subscribe Not connected. Guess i will have to speak to the IT department then?
