your system does not contain any CA files - so the certificate can’t be verified …

please check your Graylog server.log it should give you some hints on this.

Hello Jan,
Thanks. I am using the training VM ( OVA file) as ours is a test environment. I see lot of certificates present under /etc/ssl/certs directory. Is there any in particular that we should be looking for ?

/var/log/syslog doesn’t have anything related to ssl certs.
