SSL enabled reports ssl_enabled => false in the logs

[roaksoax]

This is my config:

input {
    http {
        port => 8080
        ssl_enabled => true
        ssl_key => "/etc/logstash/certs/logstash/logstash.pkcs8.key"
        ssl_certificate => "/etc/logstash/certs/logstash/logstash.crt"
        ssl_certificate_authorities => ["/etc/logstash/certs/ca/ca.crt"]
        ssl_client_authentication => required
    }
}

This is the start-up log:
