Unable to renew certs - Domain appears unreachable through HTTP from outside the local network in IPv6, though it works in IPv4

forcing cert renew works, which suggests to me that its only the checks that don’t work. my ports and whatnot all seem to work fine.

but this means that ynh auto cert renew doesn’t work, i guess?

it’s frustrating that’s its so opaque.

dig command run with my domain returns:

;; ANSWER SECTION:
mydomain.noho.st.		3600	IN	AAAA	ipv6:address:here:

does that mean one is set but only for ipv6?

i’m out of my depth there.
