Hi,

i am getting below error, after enable firewall on the logstash server.

i opened the port 5044 & 9600 on the both elasticsearch and logstash server.

[ERROR][logstash.monitoring.internal pipeline source] Failed to fetch XPack information from Elasticsearch. This is likely due to failure to reach a live Elasticsearch cluster

filter {
if [type] == "syslog" {
    grok {
      match => { "message" => "%{SYSLOGLINE}" }
    }

    date {
match => ["timestamp", "MMM d HH:mm:ss", "MMM dd HH:mm:ss"]
}
  }

}
output {
 elasticsearch {
  hosts => ["http://192.168.136.x:9200", "http://192.168.136.x:9200"]
