Hi Michael,
you can add any number of domain names to a TLS certificate. These entries are known as SAN (Subject Alternative Name). So, you want a single TLS certificate with multiple domain names instead of multiple TLS certificates each with a single domain name.
Kind regards,

I'd like to run a single vhost serving the same content under multiple FQDNs to the users
As far as I understand mod_ssl it does not seem to support to have SNI on a single vhost with multiple hostnames. I get error messages in the log file.
I am running "Apache/2.4.59 (FreeBSD) OpenSSL/1.1.1w-freebsd".
FWIW: the same concept is support with Tomcat: One connector, one default host, aliases and several SSLHostConfig elements.
Is the approach to run two vhosts here? I am sure that a SAN certificate will do the trick, but for €€€ reasons I won' able to order one.

In that case, define separate :443 vhosts for each name, and redirect to the main one.
