Filebeat Logstash "Invalid version of beats protocol: 69" error

Elastic Stack Beats
1

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
