I have a problem. When I am trying to get TLS Client Authentication work with Beats it’s fails.
I am using this guide to generate certificates and keys: https://github.com/Busindre/How-to-configure-SSL-for-FileBeat-and-Logstash-step-by-step
In Graylog Server Side Logs: javax.net.ssl.SSLHandshakeException: null cert chain
In FileBeat Logs: ERR Failed to connect: remote error: tls: bad certificate
The ca certificate was added in default java keystore.
