I think the certificate is valid now. If you still have an issue, try to add, just temporary: ssl.verification_mode: none

Really I dont know what happens because I run this command from filebeat container: curl --cacert /tmp/ca.crt -u elastic:changeme https://localhost:9200 the reponse its:

{
  "name" : "elasticsearch",
  "cluster_name" : "ll-monitoring",
  "cluster_uuid" : "g-sdsfwrRTRBB9XMiezjYWQ",
  "version" : {
    "number" : "8.10.2",
    "build_flavor" : "default",
    "build_type" : "docker",
    "build_hash" : "9d8s8d9f8d9g9hg9f8d9faca96427de4622e970e9e",

  },
  "tagline" : "You Know, for Search"
}

This is a workaround, establish HTTPS, but do not check the certificate.
Might be you don't have permission to certs. Should be investigated.
