Unable to retrieve version information from Elasticsearch nodes

Elastic Stack Kibana

Hello,

I have this error when I start kibana :

an example of the configuration of one of the cluster nodes :

# Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents
xpack.security.http.ssl:
  enabled: true
  keystore.path: /etc/elasticsearch/new/http.p12
  truststore.path: /etc/elasticsearch/new/http.p12
  client_authentication: required
  verification_mode: full
# Enable encryption and mutual authentication between cluster node
xpack.security.transport.ssl:
  enabled: true
  verification_mode: full
  client_authentication: required
  keystore.path: /etc/elasticsearch/new/node-1.p12
  truststore.path: /etc/elasticsearch/new/node-1.p12

Kibana config:


server.ssl.enabled: true
server.ssl.keystore.path: "/etc/kibana/certs/kibana1.p12"
server.ssl.truststore.path: "/etc/kibana/certs/kibana1.p12"
#server.ssl.clientAuthentication: required

# =================== System: Elasticsearch ===================
# The URLs of the Elasticsearch instances to use for all your queries.
elasticsearch.hosts: ["https://192.168.1.10:9200", "https://192.168.1.20:9200","https://192.168.1.30:9200", "https://192.168.1.40:9200", "https://192.168.1.50:9200"]
elasticsearch.ssl.certificateAuthorities: [ "/etc/kibana/certs/elasticsearch-ca.pem" ]

I think it's the kibana authentication on the cluster nodes that isn't working.
How to fix it?

Thanks in advance for your help

Is that all that is in the Kibana logs?
Is there anything in the Elasticsearch logs?

Thanks @warkolm for your answer.
I solved the problem on another ticket previously opened.
