That's your own, and could be resolved at least locally. I'm not
authoritative for decebal.nl, but it looks plausible.

That is for an upstream server. There seems to be a "server = news" line
in your leafnode configuration, and that name "news" cannot be resolved
given your current resolver configuration (predominantly
/etc/resolv.conf, but also /etc/host.conf and /etc/nsswitch.conf and
possibly unbound/bind/dnsmasq DNS configuration).  This is where you put
the name of your upstream news server that you intend to download news
from. Easiest to put a FQDN on the "server = ..." line.
