What's keeping water-reminder.app from an A

Add IPv6 for www.water-reminder.app
www.water-reminder.app has no AAAA record. Get www's IPv6 address from whoever hosts www and add it as an AAAA record. If the same server already serves both names (and its certificate covers www), you can reuse water-reminder.app's AAAA record(s) for www. How to add an AAAA record
Nameservers without IPv6
ns2.bluehost.com, ns1.bluehost.com 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.
