As a desperate attempt, I disabled IPv6
[https://wiki.centos.org/FAQ/CentOS7#head-8984faf811faccca74c7bcdd74de7467f2

workaround for the interim.

I should have been more clear, I made NO customizations except as pasted
previously. What ever the minimal install uses is what I have.

I really do not know enough about systemd, but I think this might answer
your question.
