I've generated the necessary certificates on Logstash and copied the public key to Filebeat. However SSL connection is getting failed with the below error. Any help is greatly appreciated.
Filebeat:
2018-02-06T13:24:36Z ERR Failed to publish events caused by: lumberjack protocol error
2018-02-06T13:24:36Z ERR Failed to publish events caused by: client is not connected
