[AWIPS #KZV-890448]: Unable to connect CAVE clients to local EDEX instance post-upgrade to 16.2.2

Hi Clark,

I believe the problem is caused by not having the fully-qualified EDEX server 
name in /awips2/edex/bin/setup.env (this should be the domain name which is 
resolvable from outside the system).  The "edex setup" command makes a guess as 
to what the machine name is, taken from 'ifconfig', but many times it will 
return the internal domain name, or the shortened name, rather than the full 
name.
