The certificate served over IPv6 is wrong
The certificate served over IPv6 at 2603:1036:207:2000::2 isn't valid for mail.bunnings.com.au: ERR_TLS_CERT_ALTNAME_INVALID. Often the IPv6 address points at a different server (or an old one) than IPv4 does. Make sure 2603:1036:207:2000::2 serves the same certificate as your IPv4 address.
