Logstash server is not listening on the beats input port specified. I have installed beats input plugin in logstash server, created a conf file with input port specified and pipelines file that has an entry for the conf.
The filebeat sends data just fine to elastic directly. There are other pipelines that send data to elastic search from logstash server as well.
I have Filebeat -> Logstash -> Elastic.
All servers are windows.
All versions are 6.4
