Looks like at https://hg.prosody.im/trunk/file/tip/util/prosodyctl/check.lua#l1207 `host_ok_v4` is nil because there aren't any addresses at https://hg.prosody.im/trunk/file/tip/util/prosodyctl/check.lua#l1158 .  That should probably end up as true if s2s is disabled, but not sure the best way to fit that check in
