Hoow to setup Discourse on AAAA (IPv6)?

Why? For example nodebb community worked if domain have only AAAA.

So you want an IPv6 only website? Interesting.

The server may need IPv4 connectivity to bootstrap, but having only the AAAA DNS entry should work just fine.

So now I want to use Discourse with 2 hostnames

That is not supported indeed.
