I have reviewed this question and found it to be good. What are the criteria for setting it off topic?
However the close reason is clear and just, it seems a bit odd to put this under "off topic". The question is just lacking details, but that would be more of an "unclear what you're asking" type of close reason IMHO.
From the little details that are in the question, it seems to be about networking/firewalls on a Windows Server 2016 machine, so that would actually be very much on topic.
