Error starting filebeat reading CA certificate

[jabu (jaan)]

I'm unable to start filebeat
This is the log file

So if i understand correctly the program can't locate my logstash-forwarder.

this is my 'ls' output:

jabu@ubuntu: /etc/pki/tls/certs$ ls
logstash-forwarder.crt

Not sure what the problem is..

Does Filebeat have access to the cert? What are the permissions of the file?
