Hello ,

I use filebeat to send logs to Elasticsearch , but my configuration wan't work . I use version 8.18.1.  
In Elasticsearch config file this is security settinges :

```auto
xpack.security.enabled: true

xpack.security.enrollment.enabled: true
xpack.security.http.ssl:
  enabled: true
  keystore.path: certs/http.p12
xpack.security.transport.ssl:
  enabled: true
  verification_mode: certificate
  keystore.path: certs/transport.p12
  truststore.path: certs/transport.p12
cluster.initial_master_nodes: ["node-1"]
http.host: 0.0.0.0

```

This is filebeat configuration

```auto
filebeat.inputs:
- type: filestream
  enabled: true
  id: test-input
  paths:
    - /var/log/test_logs/*.log

output.elasticsearch:
  hosts: ["https://localhost:9200"]
  api_key: "rty6v5YB6WaKLqtvBbKX:dhDckloIYuUMh6kXH2jiuy"
   ssl.certificate_authorities: ["/etc/elasticsearch/certs/http_ca.crt"]
  ssl.certificate: "/etc/elasticsearch/certs/http.p12"
  ssl.key: "/etc/elasticsearch/certs/http.p12"

```

Token for filebeat is generate with all privileges .  
When I test connection using token I am getting :

curl: (60) SSL certificate problem: self-signed certificate in certificate chain  
More details here: [curl - SSL CA Certificates](https://curl.se/docs/sslcerts.html)

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 am new to ELK stack and I don't see what I am misconfigured, does someone help me 🙂

I seams that "update-ca-certificates" solve this problem. but now is problem with token .
