Hmm.  https://www.cdn77.com/tls-test said the site had TLS 1.3, but with 
/etc/rpmdevtools/curlrc holding --tlsv1.3 and --verbose I get

*     CAfile:  /etc/pki/tls/certs/ca-bundle.crt
    CApath none

TLSv1.3 (IN), TLS alert, handshake failure (552):

followed by the original sslv3 handshake failure...  Do I need to 
specify ciphers etc?

Thanks,
