Just a stab in the dark here, but could this be a port forwarding issue on your router? Is there a router in the mix?
Yes there is a router in the mix and the port forwarding issue occurred to me as well. The box is managed by the university’s IT department and they assure me that 443 is clear all the way through.
The current idea I am exploring is that the default SSL cert that comes with FMS is inadequate (I seem to recall a mention in the server set up docs that this could be an issue), and so I am going to install a new, properly signed, cert in hopes that the changes fixes things. Stay tuned…
Although Port 443 may be open it still may be necessary to forward the port to the server machine. I have had no problem with the SSL certificate myself.
I’m making progress. It turns out that the antivirus software on the box had its own firewall that was blocking 443. After opening the port on the AV’s firewall, I can now connect to the server via sharing. However, when I try to load the test and start pages (locally on the server), I am still getting certificate errors in the browser.
