Dear all,

Im trying to setup ssl to connect filebeat to elastic

Elastic service is running in xxxxx.yy:9200

filebeat.yml  
hosts: ["xxxxx.yy:9200"]  
protocol: "https"  
ssl.certificate\_authorities: "/etc/filebeat/security/es-ca.crt"  
ssl.certificate: "/etc/filebeat/security/es-crt.crt"  
ssl.key: "/etc/filebeat/security/es.key"

I created the cert using the following commands  
Obtain key  
openssl pkcs12 -in /etc/elasticsearch/security/elastic-certificates.p12 -nocerts -nodes | sed -ne '/-BEGIN PRIVATE KEY-/,/-END PRIVATE KEY-/p' \> es.key  
Obtain the CA:  
openssl pkcs12 -in /etc/elasticsearch/security/elastic-certificates.p12 -cacerts -nokeys -chain | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' \> es-ca.crt  
Obtain the node certificate:  
openssl pkcs12 -in /etc/elasticsearch/security/elastic-certificates.p12 -clcerts -nokeys | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' \> es-cert.crt

The cluster and kibana are up and running and connected via ssl

Im trying to use certs to authenticate no basic authentication to ES

When starting filebeat I have

{"log.level":"error","@timestamp":"2022-07-08T21:55:12.183-0300","log.logger":"esclientleg","log.origin":{"file.name":"eslegclient/connection.go","file.line":235},"message":"error connecting to Elasticsearch at [https://xxxxx.yy:9200](https://xxxxx.yy:9200): 401 Unauthorized: {"error":{"root\_cause":[{"type":"security\_exception","reason":"missing authentication credentials for REST request [/]","header":{"WWW-Authenticate":["Basic realm=\"security\" charset=\"UTF-8\"","Bearer realm=\"security\"","ApiKey"]}}],"type":"security\_exception","reason":"missing authentication credentials for REST request [/]","header":{"WWW-Authenticate":["Basic realm=\"security\" charset=\"UTF-8\"","Bearer realm=\"security\"","ApiKey"]}},"status":401}","service.name":"filebeat","ecs.version":"1.6.0"}

Please help to understand what is missing.

Thanks!!!

- What does your `elasticsearc.yml` look like?
- What license are you running with?
- Where did `/etc/elasticsearch/security/elastic-certificates.p12` come from?
