iFolder client 2.1.6 on NW6.5 SP4A

iFolder will only work if I type the address "http://ipaddress:80" Any
other attempts with the secure port 443 gives "Connection with server
broken." Secure ports for GW WebAccess, Remote Manager, and Imanager
work fine. We had some certificate issues where we had to recreate the
SSL CertificateIP and DNS but iFolder secure is the only problem. I have
another user that works without typing the "http://" but still on port
80. Tried to use the LDAPCertRoot by entering path to a certificate but
nothing seems to be working. Can I just reinstall iFolder? Any other
ideas would be greatly appreciated. Thanks.
