I am hosting the logstash in EC2. And filebeat is running on my windows environment.

I consistently see this error in the logs.

And what is tripping me is that **filebeats is able to send to logstash**.

There is no loadbalancer in front of the logstash.

Please try this: [Beats can not connect to Logstash](https://discuss.elastic.co/t/beats-can-not-connect-to-logstash/224502)
