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.
–> Kibana cannot reach epr.elastic.co even though "chainpem" is set
