Elastic search: java.net.ConnectException when connecting via RestHighLevelClient

Question

I am able to access the ElasticSearch via http://127.0.0.1:9200 , however when trying to connect from the same machine via RestHighLevelClient I get the java.net.ConnectException: Connection refused.

 try { final BulkResponse response=this.restHighLevelClient.bulk(bulkRequest); } catch (final IOException exn) { LOG.error("Bulk insert failed", exn); } 

The configuration class for Elastic search client is like below.

 @Bean public RestHighLevelClient restClient() { return new RestHighLevelClient(RestClient.builder(new HttpHost("localhost", "9200", "http"))); } 

I have retained the default settings in elastic-search.yml file and debugged to be sure that host and port are correct. Any ideas please?
