Could not discover nameservers for the .invalid registry, so the parent-side checks were skipped. The authoritative side below is unaffected.
We could not retrieve registration data for test.invalid. (.invalid publishes no RDAP service in IANA's bootstrap file; rdap.org: timed out after 9999ms fetching https://rdap.org/domain/test.invalid; IANA lists no WHOIS server for .invalid)
