What is the exact address you are using to access the server *from the
server*? Are all of your systems on the same LAN segment, behind a
router?
I assume the web server is running on port 444?
How/why would port forwarding come into play? Where have you "looked
at port forwarding"? If the server and its peers are on the same LAN
segment there will not be any port forwarding. You'll simply use the IP
address (and the port if it is not the default) of the web server.
What happens when you attempt to access the web server from another
system on the LAN? If there are any error messages or browser
messages, what are they?
Is there a firewall involved, and if so, is it configured to allow
access?
