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](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
  }
}
```
