  No, I get an error with my own too simple Gemini client:

ios:write() = handshake failed: error:06FFF09C:digital envelope routines:CRYPTO_internal:unsupported algorithm

  It looks to be an issue of the TLS library not supporting the crypto
algorithm (in my case, a few months old version of LibreSSL).
