Setup Elasticsearch and Kibana on the same server with TLS/SSL

Elastic Stack Elasticsearch
2

I followed this artical. it took me while but it did worked. it was just test though

https://www.elastic.co/blog/configuring-ssl-tls-and-https-to-secure-elasticsearch-kibana-beats-and-logstash

may be you need to put full path for all .crt and .key.
that is the only difference I see on my test setup and your kibana config.

plus I didn't had following two line in my kibana.yml file
elasticsearch.ssl.certificate: certs/wildcard_cert.crt
elasticsearch.ssl.key: certs/wildcard_cert.key
