duong on Nostr: Does anybody know why I get an SSL_ERROR_ILLEGAL_PARAMETER_ALERT on ...

Does anybody know why I get an SSL_ERROR_ILLEGAL_PARAMETER_ALERT on https://www.openbsd.org./

but when I try to:
curl -Iv https://www.openbsd.org./

I get:
* SSL certificate verify ok.

I'm asking because I'm having the same issue on my own domain, using OpenBSD's httpd + acme-client
