Apr 7 22:05:11 vyos ddclient[30218]: SUCCESS: updating dontpanic42: good: IPv4 address set to aa.bb.cc.dd

ddclient[29471]: WARNING:  Could not determine an IP for dontpanic42

I’m not sure what version are you using , try to configure server :

set service dns dynamic name duckdns server www.fqdn.of.service``
