NSBS 6.5SP4 Edir iFolder 2.13

When running startifolder Apache tries loading and comes up with the error
(10037) make_secure_socket: unable to listen for connections on port 443.

iManager, Novell Webaccess, and Remote Manager do work.

TCPCON shows

IP Port 443 Remote Host Port None State Listen

I unloaded NDPS and tried to run startifolder to no avail. What can I do
to determine what is listening on 443?
