NOTE 1 - using selfsigned certs for xpath.security.http.ssl

If you want to use elasticsearch self signed certificates for the xpath.security.http.ssl, and you want kibana to connect to the cluster, you have two options:

Option 1: add this line to your kibana.yml file

elasticsearch.ssl.certificateAuthorities: [ "/etc/kibana/certs/http_ca.crt" ]

Where the http_ca.crt is a copy of /etc/elasticsearch/certs/http_ca.crt.from node 1

Option 2: add these two lines to your kibana.yml file

elasticsearch.ssl.keystore.path: [ "/etc/kibana/certs/http.p12" ]
elasticsearch.ssl.truststore.path: [ "/etc/kibana/certs/http.p12" ]

Where the http.p12 is a copy of /etc/elasticsearch/certs/http.p12 from node 1
