What's keeping matria.clinic from an A

  1. Nameservers without IPv6
    dns3.raiolanetworks.es, dns2.raiolanetworks.es, dns1.raiolanetworks.es all have no AAAA record, so a resolver that only speaks IPv6 can't look your domain up. Most DNS providers offer IPv6 nameservers; ask yours, or move DNS to one that does.
