ERR: Seems there is no Elasticsearch running on ip-10-11-1-200:8389 - Will exit

WE are trying to execute below command but getting error as ERR: Seems there is no Elasticsearch running on ip-10-11-1-200:8389 - Will exit

Command which we are trying to run is
/usr/share/elasticsearch/plugins/search-guard-6/tools/sgadmin.sh -diagnose -cd /usr/share/elasticsearch/plugins/search-guard-6/sgconfig -cn pnt-es.stg -key /etc/elasticsearch/admin/kirk.key. -cert /etc/elasticsearch/admin/kirk.key.pem -cacert /etc/elasticsearch/config/root-ca.pem -nhnv

So, is there an Elasticsearch instance running on ip-10-11-1-200:8389?

And, are you sure that the command you have provided is actually the one you are running? sgadmin normally connects to localhost by default, except you specify another host using the -h option.
