What's keeping proportaltech.cloud from an A

  1. The certificate served over IPv6 is wrong
    The certificate served over IPv6 at 2a02:4780:84:36a:3da2:f3f7:a9b3:54ee isn't valid for proportaltech.cloud: CERT_HAS_EXPIRED. Often the IPv6 address points at a different server (or an old one) than IPv4 does. Make sure 2a02:4780:84:36a:3da2:f3f7:a9b3:54ee serves the same certificate as your IPv4 address.
  2. Mail servers without IPv6
    mx2.titan.email, mx1.titan.email 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.
