It seems he has upgraded to installing via an ansible playbook.  I can get this to run all the way through, hopefully NGINX either ends up responding with a "Gateway error" or it will give me the default nginx landing page.

I have tried with a RHEL7 and CentOS7 VM, as well as in a CentOS\systemd docker container, all of which having about the same amount of luck.  I was just curious if anyone else has gotten this to work recently.
