Brand New Installation of ElasticSearch and Kibana on Windows. Kibana is not able to connect to ElasticSearch

[webdada (Breeze)]

Both are on latest 7.16.3 version.

Elasticsearch-7.16.3

1. Elasticsearch starts fine, I was able to access
   http://localhost:9200/

2. Kibana command line start error:
   log [20:15:25.611] [warning][process] Error [ProductNotSupportedSecurityError]: The client is unable to verify that the server is Elasticsearch due to security privileges on the server side. Some functionality may not be compatible if the server is running an unsupported product.

Can you share the Elasticsearch logs and the Kibana config?

[webdada (Breeze)]

Thank you @warkolm

1. I used out-of-box Kibana config, essentially no customization. Also I tried to specify the elastic host, which is my localhost, you can see part of the Kibana.yml file below.

=======================================================

The URLs of the Elasticsearch instances to use for all your queries.

Elasticsearch.hosts: ["http://localhost:9200"]

Kibana uses an index in Elasticsearch to store saved searches, visualizations and

dashboards. Kibana creates a new index if the index doesn't already exist.

#kibana.index: ".kibana"

The default application to load.

#kibana.defaultAppId: "home"
