Hi @Kunal_Rastogi In order to get help faster, please make sure to clearly state your problem in the summary. Now to back to the issue: ```auto security_exception: missing authentication credentials for REST request [/_nodes?filter_path=nodes.*.version%2Cnodes.*.http.publish_address%2Cnodes.*.ip] ``` First I would double check you can access Elasticsearch instance with credentials you set in kibana.yml ```auto curl --user -X GET "http://:/?pretty" ``` You can also check the similar [issue](https://discuss.elastic.co/t/kibana-configure-security-missing-authentication-credentials-for-rest-request/256790) and its troubleshooting.
