TLS Client authentication - null cert chain

Graylog Central (peer support)
1

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.

Please describe exactly what you’ve done and provide the complete configuration of all involved components as well as the commands you’ve executed including their complete output.

It’s all good now. I don’t know why but adding CA.crt to TLS Client Auth Trusted Certs solved problem!
Thanks
