Ah, sorry - I had missed that https://www.domain.com, https://domain.com,
and https://www.domain2.com all worked ok on IPv4. It is only
https://domain2.com that presents an unwanted certificate.

(And it presents the certificate for domain.com, even though
www.domain.com is configured as the default_server.)

Do you have four separate ssl certificate files, each of which is valid
for a single server name?

Or do you have one ssl certificate file which is valid for multiple
server names?

One guess - is there any chance that the contents of the ssl_certificate
file that applies in the domain2.com server{} block is actually the
domain.com certificate? (Probably not, because the IPv6 connection should
be using the same ssl_certificate, and no error was reported there.)

Other than that, I don't know. Can you provide a complete config and
test commands that someone else can use to recreate the problem?

Or, to rule out any strange IPv4/IPv6 interaction -- do you see the same
behaviour when you remove all of the IPv6 config?

Good luck with it,
