**Versions** (Opensearch 2.3x ): I’m trying to connect to an OpenSearch service running in AWS from my Java rest high level client . I have created my service without any VPC configuration and have set up a master user and password . I’m able to access the service with the curl command to create an index and also perform a bulk operation. curl -XPOST -u ‘master\_username:master\_password’ ‘https://search-\*\*\*\*\*\*\*\*/\_bulk’ --data-binary ‘@loaddata.json’ -H ‘Content-Type: application/json’ Below is the code I have written to connect to the service . final CredentialsProvider credentialsProvider = new BasicCredentialsProvider(); credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(“master\_username”, “master\_password”)); ``` //Create a client. RestClientBuilder builder = RestClient.builder(new HttpHost(host)) .setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() { @Override public HttpAsyncClientBuilder customizeHttpClient(HttpAsyncClientBuilder httpClientBuilder) { return httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider); } }); RestHighLevelClient client = new RestHighLevelClient(builder); CreateIndexRequest createIndexRequest = new CreateIndexRequest("custom-index"); ``` But the above code is trying to connect to the service and throwing a connection timeout error and this particular domain url is being added to the deny List.

You need to provide host, port and scheme in HttpHost constructor. If your cluster in on https port would be 443 HttpHost(, 443, https) HttpHost(, 9200, http) ---
