Hi,

the domain specification in the configuration reported on launchpad:

 [Resolve]
 Cache=no
 DNS=127.0.0.54
 Domains=~.local.org.com

is invalid:

 systemd-resolved[13415]: Failed to add search domain '~.local.org.com', ignoring: Invalid argument

The correct form should be without the dot:

 Domains=~local.org.com

Can you ask to fix that configuration error and try again? Otherwise,
queries for the local.org.com domain are not routed to the local
dnsmasq instance.
