Trouble getting secondary axfr with 4.1.0

DNS seems OK with one server, but attempting to us buddyns.com as secondary fails.
I am using debian jessie. Is sudo systemctl restart nsd all I need to serve new changes to nsd.conf?

Below is the start of my nsd.conf. Any suggestions to get test such as
$ dig +tcp axfr @104.219.54.106 ns1.cibolo.us
to show a good transfer?

Thanks,

John Griessen

DNS seems OK with one server, but attempting to us buddyns.com as secondary fails.

   Could you be more explicit about the failure symptoms?

zone:
# this server is master, 104.245.34.178 is a secondary
  name: cibolo.us
  zonefile: cibolo.us.zone
  provide-xfr: 104.245.34.178 NOKEY
# notify: 104.245.34.178 NOKEY
  # allow ALL the following addresses! BuddyNS employs them all.
# notify: 173.244.206.26 NOKEY
  provide-xfr: 173.244.206.26 NOKEY
# notify: 88.198.106.11 NOKEY
  provide-xfr: 88.198.106.11 NOKEY

   If the failure mode you're concerned about is that the slave does
   not pick up zone immediately, this could be because you've
   suppressed the 'notify:' directives.

   If you haven't already done so, I'ld suggest using Zonemaster or
   DNSViz to verify nameserver function and identify problems.

   Here are some recent results from these tools:
