Well, yes and no. Running these commands made it eventually work on an 
isolated system with IPv4 and IPv6 addresses assigned to the NIC:

systemctl stop    firewalld
systemctl disable firewalld
shutdown -r now Preventive reboot after disabling firewalld.;sleep 1;logout

Systems running with IPv6 only, not so much.

Further testing shows that the web browser determines success or 
failure.

Access the web UI by specifying the system's IPv4 address, numerically 
or as a domain name, and everything works; access the web UI by 
specifying the system's IPv6 address, numerically or as a domain name, 
and it all breaks. And happens in 2017?

I was hoping to avoid assigning IPv4 addresses to my perfSONAR nodes ...
