Right now lemmy.ml doesn’t have an AAAA record, if the server has a public IPv6 perhaps you just need to add it. Make sure you’re binding to :: and not to 0.0.0.0.
You could test by disconnecting your computer (not the server!) from the v4 Internet with ip route del default, assuming you have IPv6 connectivity. Do ip route showdefault first so that you can ip route adddefault via … later to restore your v4 access. If your ISP doesn’t offer v6 you’d have to fiddle with Teredo, but it’s worth it because then you have end to end connectivity with everyone else on the v6 Internet with no NAT.
