[gnutls-help] Is X448 supported?

[John Jiang]

Hi,
Just want to confirm if X448 is supported by GnuTLS 3.6.10.

Used the below OpenSSL command to try to connect a GnuTLS server,
openssl s_client -tls1_2 -cipher ECDHE-RSA-AES128-GCM-SHA256 -groups X448
host:port
The server raised handshake error: No supported cipher suites have been
found.

But if specified X25519, it worked fine.
