That's because the second vhosts has IPv6 listening socket on port
80 configured with "ipv6only=off", so it accepted both IPv6 and
IPv4 connections. In contrast, IPv6 socket on port 443 (the one
used for https) is _not_ configured with "ipv6only=off", so it
only accepts IPv6 connections, but not IPv4. And the separate
IPv4 listening socket on port 443 was only configured in the first
vhost, but not in the second one. As such, all IPv4 https
connections were handled by the first vhost only.

Glad it works now, and hope the previous behaviour is clear now as
well: it is a result of no IPv4 listening socket on port 443 in
the second vhost in the original configuration.
