Hi,

When i want to validate the logstash server certificate with this command :

```auto
curl -v --cacert /etc/logstash/config/certs/logstash.crt https://logstash.ad-it.fr:5044
Rebuilt URL to: https://192.168.1.30:5044/
* Trying 192.168.1.30...
* TCP_NODELAY set
* connect to 192.168.1.30 port 5044 failed: Connection refused
* Failed to connect to 192.168.1.30 port 5044: Connection refused
* Closing connection 0
curl: (7) Failed to connect to 192.168.1.30 port 5044: Connection refused

```

Best regards,

/etc/logstash/conf.d/example.yml

```auto
input {
  beats {
    port => 5044
    ssl => true
    ssl_certificate_authorities => ["/etc/logstash/config/certs/ca.crt"]
    ssl_key => "/etc/logstash/config/certs/logstash.pkcs8.key"
    ssl_certificate => "/etc/logstash/config/certs/logstash.crt"
    ssl_verify_mode => "peer"
  }
}
output {
  elasticsearch {

    user => 'logstash_writer'
    password => 'changeme'
    index => 'logstash-%{+YYYY.MM.dd}'
  }
}

```

Do you have a firewall installed on that host that you need to open up?  
For example on CentOS/RHEL 7 firewalld is turned on by default and you need to open up a port to allow traffic through.
