What's keeping tt00055.shop from an A
tt00055.shop is an alias of 5ngu1464fpb3gu.dns.foocname.cc, which has no IPv6 tt00055.shop is a CNAME, so it can't also have its own AAAA record.

Mail servers without IPv6 Your domain's mail goes to its own address, which has no AAAA record.
Nameservers without IPv6 a.share-dns.com, b.share-dns.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.
