Hi,  
I am doing a helm-Kubernetes deployment of Elastic cluster and I am using company signed CA certificates. Elasticsearch is coming up with the certificate, however Kibana gives this error. Looking for help on understanding what this error is supposed to mean.

\< / \>  
"type":"log","@timestamp":"yyyy-mm-ddT07:26:25+00:00","tags":["error","elasticsearch-service"],"pid":7,"message":"Unable to retrieve version information from Elasticsearch nodes. unable to get issuer certificate"}  
\< / \>
