What are the unsupported Kexalgorithms and Ciphers in FIPS mode enabled?

Issue

• One of the KexAlgorithms configuration in /etc/ssh/sshd_config file is causing issues with FIPS.

root@example ~]# sshd -T | grep -i kex
"curve25519-sha256" is not allowed in FIPS mode
/etc/ssh/sshd_config line 180: Bad SSH2 KexAlgorithms 'curve25519-sha256,curve25519-sha256@libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group16-sha512,diffie-hellman-group18-sha512,diffie-hellman-group14-sha256'.
