I have reviewed this question and found it to be good. What are the criteria for setting it off topic?
Read the yellow box. OP doesn't tell us anything about his environment. It can be reopened when it is improved.
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.
