I have installed the eck stack on the top of the Kubernetes and i want to install the fleet server on the kubernetes and on the bare metal server with the custom tls certificate. My ECK stack is working properly fine on my custom TLS certificate but when i try to generate the fleet certs with the elasticsearch util it fails to validate the ca certs and other certs. ---

Could you please provide the manifests you are using? Maybe also the error log? Could you also share how you are using "the elasticsearch util"? Did you use something like openssl to validate that the chain is actually valid?
