I don't have any component before ES. It is just configured with Mutual TLS.
I have done a tcpdump and I see that Elastic service is requiring the client certificate to rally but it is not sending them to ES.
When I run:
curl --cacert /tmp/cacert.pem --cert /tmp/client_cert.pem --key /tmp/client_key.pem https://10.10.10.10:31504
I see the error mentioned in the first post.
