What's keeping sipena.online from an A

Nameservers without IPv6
ns1.rumahweb.com, ns2.rumahweb.com, ns3.rumahweb.net, ns4.rumahweb.net 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.
