Получение «ошибки 7 cURL» подключение к серверам ElasticSearch с использованием PHP-клиента ElasticSearch

Попытка соединиться с ES, размещенным с ObjectRocket, но получить следующую ошибку …

Fatal error: Uncaught exception 'Elasticsearch\Common\Exceptions\TransportException' with message 'cURL error 7: See http://curl.haxx.se/libcurl/c/libcurl-errors.html'
in /var/www/html/vendor/elasticsearch/elasticsearch/src/Elasticsearch/Connections/Connection.php:201 Stack trace:

Мой код PHP:

<?php

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

require 'vendor/autoload.php';

use Elasticsearch;
use Elasticsearch\ClientBuilder;

$multiHandler = ClientBuilder::multiHandler();

$hosts = [
'http://user:[email protected]:10183',
'http://user:[email protected]:10183',
'http://user:[email protected]:10183',
'http://user:[email protected]:10183'
];

$client = ClientBuilder::create()->setHosts($hosts)->setHandler($multiHandler)->build();

$params = [
'index' => 'my_index',
'type' => 'my_type',
'id' => 'my_id',
'body' => [
'testField' => 'abc'
]
];

$response = $client->index($params);
print_r($response);
?>

Но если я бегу curl команда из терминала это у меня нет проблем с подключением …

curl -XGET http://user:[email protected]:10183
