Issue

  • After regenerating the cluster certificate, OpenSSL shows different TLS versions and ciphers for node management LIFs.
  • Running openssl s_client -connect <node_management_lif>:443 returns:
New, TLSv1.3, Cipher is TLS_AES_256_GCM_SHA384 for one node
and
New, TLSv1.2, Cipher is ECDHE-RSA-AES256-GCM-SHA384 for the remaining nodes
