No, I closed the ticket because I reinstalled the entire ELK.

In the new install I have uploaded our company cacert to (/usr/share/logstash/jdk/lib/security and /usr/share/elasticsearch/jdk/lib/security).

This has not helped because the “pemchain” contains self-signed Cert.

Als next Step I added the option “NODE\_EXTRA\_CA\_CERTS="/etc/kibana/CA\_Bundle\_2024.pem" in the file “kibana” in directory “/usr/share/kibana/bin/”

And restarted KIBANA. No change, I have given up.
