I try connection from kibana to elastic node with curl:
curl -u <username>:<password> https://localhost:9200 --insecure -v

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.

i try to turn off https and auth.

elasticsearch.hosts: ["http://10.0.9.51:9200"]
elasticsearch.ssl.verificationMode: none
# Enable security features
xpack.security.enabled: false

xpack.security.enrollment.enabled: true

# Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents
xpack.security.http.ssl:
  enabled: false
  keystore.path: certs/http.p12

# Enable encryption and mutual authentication between cluster nodes
xpack.security.transport.ssl:
  enabled: true
  verification_mode: certificate
  keystore.path: certs/elastic-certificates.p12
  truststore.path: certs/elastic-certificates.p12

then i try curl on http

curl -X GET "http://10.0.9.51:9200?pretty"
{
  "name" : "dca-elk-n1",
  "cluster_name" : "dca",
