The certificate served over IPv6 is wrong
The certificate served over IPv6 at 2a11:4881:1:ce1b::1 isn't valid for verstraaten-it-services.com: ERR_TLS_CERT_ALTNAME_INVALID. Often the IPv6 address points at a different server (or an old one) than IPv4 does. Make sure 2a11:4881:1:ce1b::1 serves the same certificate as your IPv4 address.
