OpenSSL 1.1.1l-freebsd  24 Aug 2021

I will try to remove the expired cert and see what happens.

The server (v.20.0.13) uses security/ca_root_nss, the client apparently 
does not, it does not look in /usr/local/share/certs or /usr/local/etc/ssl

And, Windows and Mac clients does not exhibit this behaviour.
