Spring Resttemplate with BasicCredentialsProvider return 401 unathorized

Question

Problem: I try to make rest call using Resttemplate but it gives 401 status code after that retries once again and gives 200 status code. So every time it makes two calls. So My question is why Resttemplate doesn't use BasicCredentialsProvider in a first call?

Below is my RestTemplate configuration.

@Bean
public CloseableHttpClient httpClient() {

        try {

            BasicCredentialsProvider credentialsProvider = new BasicCredentialsProvider();
            credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("XXXX", "XXXXX"));

        CloseableHttpClient httpclient = HttpClientBuilder
                .create()
                .setDefaultCredentialsProvider(credentialsProvider)
                .setDefaultHeaders(headers)
                .build();
        return httpclient;
    }
    catch (Exception e) {
        throw e;
    }
}

@Bean
public RestTemplate restTemplate(){

     RestTemplate template = new RestTemplate();
     HttpComponentsClientHttpRequestFactory requestFactory = new 
     HttpComponentsClientHttpRequestFactory(httpClient());
     template.setRequestFactory(requestFactory);

     return template ;
}

RestTemplate Call

template.getForObject(...;

So here am I missing something which is not taking credential in the first call?

Below are the httpclient related logs

I had made the same call with HTTPClient directly and it doesn't have any problem.

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet getRequest = new HttpGet(url);
getRequest.addHeader("content-type", "application/vnd.nativ.mio.v1+json");

BasicCredentialsProvider credentialsProvider = new BasicCredentialsProvider();
credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("XXXXX", "XXXX"));
httpClient.setCredentialsProvider(credentialsProvider);

HttpResponse response = httpClient.execute(getRequest);
