Yesterday, I installed a new FileMaker Server 12 instance on a new MtLion Server. All updates applied in OS ( 10.8.5) , FileMaker 188.8.131.521 and Java land 7.0.45.
I can open FileMaker Server Admin local to the machine.
I have Enabled access restrictions for IP addresses that I want to allow Admin access in the General Settings>Admin Console area
SSL communication is turned on.
I can get to the server info page
I can launch the applet but when I do I get "Admin Console could not start: Admin Server Manager unavailable."
Wireshark shows communcation going out but nothing coming back...
I cleared the Java caches and reset on both sides.
