kindly help to resolve this issue.

It looks like Kibana has been configured to expect Elasticsearch to be running at the host name "elasticsearch" on port "9200", possibly via the elasticsearch.url setting in your kibana.yml. Is "elasticsearch" a valid host name on your system? If you're running Elasticsearch locally you could configure elasticsearch.url: "http://localhost:9200" (the default) so that Kibana connects to Elasticsearch on your localhost.
