I am running Elasticsearch and Kibana 8.11.3 version on ubuntu VM using docker.  
If I try to connect the Elasticsearch with PowerBI through API key. It is showing the below error.  
Error Message: -"The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel."
