Then here's another question. If the server has a huge list of ciphers,

in a failed handshake) while there are many others that can be used?

I wasn't entirely paying attention when this conversation started, so not
sure what's happening and what order it's happening in.

It could be a configuration that is trying to avoid downgrade attacks, see
the article I cited on "vulnerabilities".

Or both of you could be confused about what you're actually supporting.

You might try going to the IFS in PASE and exploring the TLS exchange via
the openssl s_client command
