I used es in my java-program.But it can not worked.It mention me this message "java.net.ConnectException: Connection timed out: no further information".
I had try to test my server like (firewired\ip\port\username), all of them are ok.
And i had use "curl" command in cmd,it worked like this:

Here is my code and my error, how can fix it to do, please a lot.

public static void main(String[] args) {
    long startTime = DateUtil.getLastDaysTimestamp(1);
    long endTime = DateUtil.getLastDaysTimestamp(0) - 1;
    final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
    credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("elastic", "elasticpass"));
    RestClientBuilder restClientBuilder = null;
    try {
        restClientBuilder = RestClient.builder(
                new HttpHost(InetAddress.getByName("127.0.0.1"), 9200, "http")
        ).setHttpClientConfigCallback(
                httpAsyncClientBuilder -> httpAsyncClientBuilder.setDefaultCredentialsProvider(credentialsProvider)
        ).setRequestConfigCallback(new RestClientBuilder.RequestConfigCallback() {
            @Override
            public RequestConfig.Builder customizeRequestConfig(RequestConfig.Builder builder) {
                builder.setConnectTimeout(30*60*1000);
                builder.setSocketTimeout(60000);
                return builder;
            }
        });

        //set header, after es6.0 need change Content-type to application/json
        Header[] defaultHeaders = new Header[]{
                new BasicHeader("Content-type", "application/json")
        };
        restClientBuilder.setDefaultHeaders(defaultHeaders);
    }catch (Exception e){
        e.printStackTrace();
    }
    RestHighLevelClient restHighLevelClient = new RestHighLevelClient(restClientBuilder);

    SearchRequest searchRequest = new SearchRequest("logstash-nginxaccess-*");

    SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
    searchSourceBuilder.query(
            QueryBuilders.boolQuery()
                    .must(QueryBuilders.matchAllQuery())
                    .must(QueryBuilders.rangeQuery("@timestamp").gte(startTime).lte(endTime))
    )
            .timeout(new TimeValue(60*1000,TimeUnit.SECONDS))
            .size(100);

    //TermsAggregationBuilder termsAggregationBuilder = AggregationBuilders.terms()
    System.out.println(searchSourceBuilder.toString());
    searchRequest.source(searchSourceBuilder);

    SearchResponse searchResponse = null;
    try {
        searchResponse = restHighLevelClient.search(searchRequest, RequestOptions.DEFAULT);
    } catch (IOException e) {
        e.printStackTrace();
    }
    System.out.println(searchResponse);
}
