Ok, we’re spinning our wheels because there’s too much setup that’s unknown here.
Let me make a suggestion at this point, this thread
has a wealth of information about setting up NS as a web server and how it’s handled ‘under the hood’, I suggest skimming through this thread and see if there’s something there that can help you.
If that doesn’t do it, and none of the experts chime in here, a few more screenshots of your vhosts and dns pages as well as your directories may help us narrow this down.
