Cannot resolve DNS

[ziggysdomain]

Hi. Cannot resolve DNS - from the log. Have a NO-IP account and have entered the login credentials and the host name registered with them. Am getting:
WARN cannot DNS resolve ******.ddns.net after 5 tries: lookup *********.ddns.net: no such host

Any ideas where I’m going wrong? Am using the official ddns.updater app on TrueNAS-SCALE-22.12.2

try changing RESOLVER_ADDRESS? Maybe the DNS server is not working properly. If that doesn't solve it, please share a more complete log.
