I feel like I am on a different problem track and should stop making noise here... but wanted to followup on my previous comments for anyone else who comes along.
I figured out that the appliance firewall blocks ICMP. Therefore do not expect it to respond to pings unless you disable the firewall (/etc/wemi/utils/disable_firewall.sh). It is fine to have the firewall on unless you need ICMP it for testing (I think).
The console gave me confusing results because it would work in Chrome but not in IE... only I didn't notice the pattern for a while. Turns out I needed TLS 1.1 enabled in IE (IE 10... why wasn't it enabled already? I dunno.)
Anyway, I suspect if I had not focused on pinging and had tried Chrome first I would have connected to my first install.
Now I have successfully AppCapture'd, Assign'ed and Agent'ed to get a simple app on my test client. Modest success. Now can do real testing.
Good luck.
