Logstash with Filebeat transfer over TLS

[pleegor]

Hi,

I have configured ELK and client with filebeat as 2 VMs on Vagnrant/VirtualBox. When enable TLS I am not able ship logs to logstash.
/etc/logstash/conf.d/02-beats-input.conf

input {
  beats {
    port => 5044
    type => "JSON"
    ssl => true
    ssl_certificate => "/etc/pki/tls/certs/logstash-forwarder.crt"
    ssl_key => "/etc/pki/tls/private/logstash-forwarder.key"
    congestion_thershold => 1000
  }
}

This are the errors I see when I am running filebeat in debug mode:

When I remove SSL part of logstash.config logs are being shipped to Logstash without any problem. I also able to telnet on port 5044 and when I run curl -v --cacert logstash-forwarder.crt http://192.168.0.10:5044 I get the following:

curl -v --cacert logstash-forwarder.crt https://192.168.0.10:5044
* About to connect() to 192.168.0.10 port 5044 (#0)
*   Trying 192.168.0.10...

* Initializing NSS with certpath: sql:/etc/pki/nssdb
* Closing connection 0
curl: (77) Problem with the SSL CA cert (path? access rights?)

When SSL part of in place none (telnet and curl) work. I can provide filebeat.yml if it is needed. Did anyone face similar problem?
