The certificate served over IPv6 is wrong
The certificate served over IPv6 at 2a01:4f8:d0a:27bd::2 isn't valid for shopify-order-flow.com: ERR_TLS_CERT_ALTNAME_INVALID. Often the IPv6 address points at a different server (or an old one) than IPv4 does. Make sure 2a01:4f8:d0a:27bd::2 serves the same certificate as your IPv4 address.
