ping: test.nextdns.io: Name or service not known
OS: Ubuntu 22.04
NextDNS configuration as recommended for systemd-resolved.
After enabling DNSSEC=yes in '/etc/systemd/resolved.conf':
- Web browser (https://my.nextdns.io): unable to check status
$ ping test.nextdns.io ping: test.nextdns.io: Name or service not known
$ resolvectl query test.nextdns.io test.nextdns.io: resolve call failed: DNSSEC validation failed: no-signature
With other sites currently there is no problem (e.g. nextdns.io).
Is it due to incorrect server (test.nextdns.io) configuration?
