I was able to upgrade from 20.7.8_4 to 21.1 without any issues this time, so for me clearing house on the all the CA and generated certificates for the old Let's Encrypt CAs sorted it out.

lighttpd developer here.   lighttpd developers generally fix issues very quickly IFF those issues are reported to the lighttpd developers at https://redmine.lighttpd.net/projects/lighttpd/issues

When configuring certificates in lighttpd, please include the intermediate certificates.  Let's Encrypt provides fullchain.pem, and that is the file that should be configured for lighttpd to use.

There is extensive documentation for how to configure lighttpd TLS modules:
