Yeah, I've been a bit confused about that myself. I manually frigged the httpd.conf (I know I will wipe out the changes with an expand-template), and found that some operations failed due to attempting a http lookup instead of https. Changing the URL would work correctly. This means that it is either SSL-Explorer not properly specifying URLS, or mod_proxy not correctly translating the urls, or some interaction of the two. Connecting directly to the SSL-Explorer port as https works correctly.
I have actually uninstalled SSL-Explorer and tried the open source fork (Adito/OpenVPN-ALS), but that isn't working for me at all. <sigh>
Maybe I'll just have to live without it, but it is a pretty cool system. It is just blocked by many firewalls that object to https on port 28081.
