On a Ubuntu 20.04 AWS EC2 instance, an application need to resolve .local zone. It is a private zone, created in Route53, accessible only from the VPC. From a CentOS 7 instance (without systemd-resolved) it is resolved without problems. The problem is on the Ubuntu instance (with systemd-resolved installed by default):
$ nslookup kafka.local

** server can't find kafka.local: SERVFAIL

Is there any possible configuration to make systemd-resolved to resolve this .local zone correctly?
