When I set the ssl ciphers list in the EC2 instance to the below one,
ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256
the instance fails the health check from the application load balancer.
How can I find which ciphers in the cipher list on the server is supported/not supported by the load balancer? I have tried to enable the same set of ciphers in the server and on the load balancer's listener configuration also.
Also, when HIGH:!aNULL:!MD5
is set on the server, the instance does not fail the health checks from the load balancer.
