RestClient Elastic Search external host

I am trying to hit an external URL ES server using Java Springboot.

The corresponding cURL is:

curl -XGET 'xyz.elasticsearch.abc.consul:9200/data/values/_search?' -d '{"query"
:{"bool":{"must":{"match":{"_type__s":"filter-variable"}}}}}'

            RestHighLevelClient client = new RestHighLevelClient(
                    RestClient.builder(
                            new HttpHost("xyz.elasticsearch.abc.consul", 9200, "http")));
            SearchRequest searchRequest = new SearchRequest("data");
            SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
            searchSourceBuilder.query(QueryBuilders.matchQuery("_type__s", "filter-variable"));
            searchRequest.source(searchSourceBuilder);
            SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);
            SearchHits hits = searchResponse.getHits();
            SearchHit[] searchHits = hits.getHits();
            for (SearchHit hit : searchHits) {
                Map<String, Object> sourceAsMap = hit.getSourceAsMap();
                System.out.println("name  "+ sourceAsMap.get("name"));
            }
            client.close();

With this I end up receiving Caused by: java.net.ConnectException: Connection refused (Connection refused) while curl still works in the same machine. Any help would be great.
