Hi, I am getting error while connecting to elasticSearch using HighLeavelClient. My elastic Search instance is Running on localhost with bind and publish address 127.0.0.1:9200 and is working fine with Postman (I have created one index and added a document as well) . But when I am trying to create connection using java code using HTTPHighLevelClient I am getting "IOException java.net.ConnectException: Connection refused" error. I have tested using both localhost and 127.0.0.1 IP in code - ```auto new RestHighLevelClient(RestClient.builder(new HttpHost("localhost", 9200, "http"), new HttpHost("localhost", 9201, "http"))); ``` elastic search console Logs - ```auto [2019-04-23T10:53:34,289][WARN][o.e.x.s.a.s.m.NativeRoleMappingStore] [INGGNLAP0270] Failed to clear cache for realms [[]] [2019-04-23T10:53:34,323][INFO][o.e.l.LicenseService] [INGGNLAP0270] license [e78802c4-9436-42a3-9a61-be9068b90684] mode [basic] - valid [2019-04-23T10:53:34,330][INFO][o.e.g.GatewayService] [INGGNLAP0270] recovered [1] indices into cluster_state [2019-04-23T10:53:34,704][INFO][o.e.c.r.a.AllocationService] [INGGNLAP0270] Cluster health status changed from [RED] to [YELLOW] (reason: [shards started [[audit][0]] ...]).

In case it changes anything, I'd use `127.0.0.1` instead of `localhost`. Not sure what is wrong though. ---

Can you just try with the low level client and share your code on GitHub then? ---

Hi , Sorry for late reply. I cannot share the code on Github. I am able to connect elasticsearch instance using spring boot project .So, I think there is some issue in permissions of my AWS lambda functions. ---
