I have set two VMs, one Ubuntu where I've installed ELK and another CentOS where I've installed Filebeat. I want to forward CentOS logs to ELK via filebeat. I have configured all my files correctly (I think) but when I run filebeat to forward logs to Logstash it gives the above error. If I change the output from logstash to Elasticsearch, the filebeat stops working and it gives the error **Failed to start Filebeat sends log files to L..........**

**This is my Logstash COnfiguration in /etc/logstash/logstash.yml file**

```auto
path.data: /var/lib/logstash
path.logs: /var/log/logstash

```

**/logstash/conf.d/filebeat.conf file...**

```auto
input {
  beats {
    port => 5044
          }

}

filter {

}

output {

  elasticsearch {

    hosts => ["http://localhost:9200"]
    index => "%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"
    user => "elastic"
    password => "my_elastic_password"

```

**selasticsearch.yml file...**

```auto
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
xpack.security.enabled: true
xpack.security.enrollment.enabled: true
xpack.security.http.ssl:
  enabled: true

  truststore.path: certs/transport.p12
cluster.initial_master_nodes: ["hilmand-virtual-machine"]

```

**filebeat.yml file...**

```auto
filebeat.inputs:
- type: log

filebeat.config.modules:
 path: ${path.config}/modules.d/*.yml

**output.logstash:

```

**all the ssl certificate related stuff is commented out**
