What's keeping kai-services.online from an A

  1. The certificate served over IPv6 is wrong
    The certificate served over IPv6 at 2a00:f940:2:2:1:1:0:173 isn't valid for kai-services.online: DEPTH_ZERO_SELF_SIGNED_CERT. Often the IPv6 address points at a different server (or an old one) than IPv4 does. Make sure 2a00:f940:2:2:1:1:0:173 serves the same certificate as your IPv4 address.
  2. Mail servers without IPv6
    mx1.hosting.reg.ru, mx2.hosting.reg.ru 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
    ns2.hosting.reg.ru, ns1.hosting.reg.ru 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.
