Hello,

I'm trying to configure logs for my Elasticsearch cluster, by following this:

and even though i set verification_mode to none, i still getting 401

{"log.level":"error","@timestamp":"2023-09-19T19:13:02.623Z","log.logger":"publisher_pipeline_output","log.origin":{"file.name":"pipeline/client_worker.go","file.line":148},"message":"Failed to connect to backoff(elasticsearch(https://es02:9200)): 401 Unauthorized: {"error":{"root_cause":[{"type":"security_exception","reason":"unable to authenticate user [elastic] for REST request [/]","header":{"WWW-Authenticate":["Basic realm=\"security\" charset=\"UTF-8\"","Bearer realm=\"security\"","ApiKey"]}}],"type":"security_exception","reason":"unable to authenticate user [elastic] 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"}

I tried both of these methods, however without any luck(

root@dos:/opt/elk# grep -A2 ' filebeat:' docker-compose.override.yml
  filebeat:
    command: "--strict.perms=false -e -E output.elasticsearch.ssl.verification_mode=none -E 'output.elasticsearch.hosts=[https://es01:9200,https://es02:9200,https://es03:9200]' -E output.elasticsearch.username=elastic -E output.elasticsearch.password=${ELASTIC_PASSWORD}"
