Nameservers have IPv6
No nameserver has an AAAA record — an IPv6-only resolver can't reach this domain's DNS.

What's keeping polygoneconseil.org from an A

  1. The certificate served over IPv6 is wrong
    The certificate served over IPv6 at 2001:41d0:301::30 isn't valid for polygoneconseil.org: ERR_TLS_CERT_ALTNAME_INVALID. Often the IPv6 address points at a different server (or an old one) than IPv4 does. Make sure 2001:41d0:301::30 serves the same certificate as your IPv4 address.
  2. Mail servers without IPv6
    mx1.mail.ovh.net, mx2.mail.ovh.net, mx3.mail.ovh.net have no AAAA record, so mail from IPv6-only servers can't reach them directly. If a provider runs your mail, that's their setting; if you run it, add AAAA records for these hosts.
  3. Nameservers without IPv6
    ns200.anycast.me, dns200.anycast.me 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.
