When I tried to set up Logstash without TLS, I kept receiving an infuriating "connection reset by peer error, no matter what options I used, and absolutely nothing on this forum was useful in solving it.
I'm now trying to set up TLS to see if this solves the issue, but I already have a Let's Encrypt cert so I don't want to generate a self-signed like the docs suggest. However, I also can't find any documentation on how you can use a third-party SSL cert with Logstash.
I anyone who has accomplished this willing to share their Logstash input and Filebeat output configurations with respect to the SSL certificates?
