I appreciate the suggestion. It might be worth noting that documentation
should include -u for authentication headers IMO, not that I'm expert.

curl (and telnet) to the server's DNS address has the connection refused
(to http and https to FQDN or localhost) but by ip address almost works:
"Empty reply from server" tho telnet works.

curl --insecure -u bad_user:bad_password -X POST -H "Content-Type:
application/json" -d '{ "command": "config-get", "service": [ "dhcp4" ] }'
xxx.xxx.xxx.xxx:8000
