How to enable Elastic Search REST API Accessible using IP Address?

By default http transport and internal elasticsearch transport only listens to localhost. If you want to access Elasticsearch from the host other than localhost then try adding following configurations in config/elasticsearch.yml. Also, 9200 port should be opened. localhost
transport.tcp.port: 9300
http.port: 9200
Here, as allow access from any host within the network.
