SSL problem

I found a problem when i generate SSL certificate for filebeats.

2016/08/31 03:18:31.828989 transport.go:125: ERR SSL client failed to connect with: x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "serial:14097344026580015968")

Any help... Thank you
