Logstash Lumberjack Cert

Elastic Stack Logstash
4

I am in the same situation as you. I configured everything like here: https://www.elastic.co/guide/en/logstash/current/ls-to-ls.html

But i get sometimes PEER_DID_NOT_RETURN_A_CERTIFICATE or SSLV3_ALERT_CERTIFICATE_UNKNOWN

my configs:
upstream:

output {
  lumberjack {
    hosts => "agg_hag1.domain.com"
    port => 5055
    ssl_certificate => "/home/logstash/certs/agg_hag1.crt"
    codec => "json"
  }
}

downstream:

input {
  beats {
    port => 5055
    codec => "json"
    ssl => true
    ssl_certificate => "/home/logstash/certs/agg_hag1.crt"
    ssl_certificate_authorities => "/home/logstash/certs/domain-ca-pem.crt"
    ssl_key => "/home/logstash/certs/agg_hag1-des-v1.pem"
    ssl_key_passphrase => "PWD"
#    ssl_verify_mode => none
#    tls_min_version => 1.2
  }
}
