php - No alive nodes. All the 1 nodes seem to be down

one text

I am trying to use Elasticsearch 8.1 using laravel. My elasticsearch instance is running at port 9200. https://localhost:9200 returns me

{
  "name" : "node-1",
  "cluster_name" : "my-application",
  "cluster_uuid" : "7wIGGqhBS5OXfV0E4J53GQ",
  "version" : {
    "number" : "8.0.1",
    "build_flavor" : "default",
    "build_type" : "tar",
    "build_hash" : "801d9ccc7c2ee0f2cb121bbe22ab5af77a902372",
    "build_date" : "2022-02-24T13:55:40.601285296Z",
    "build_snapshot" : false,
    "lucene_version" : "9.0.0",
    "minimum_wire_compatibility_version" : "7.17.0",
    "minimum_index_compatibility_version" : "7.0.0"
  },
  "tagline" : "You Know, for Search"
}

Inside Laravel, I have following lines of code.

$hosts = [
    'http://127.0.0.1:9200',
];
$client = ClientBuilder::create()
    ->setSSLVerification(false)
    ->setHosts($hosts)
    ->build();

$params = [
    'index' => 'sample_index',
    'id' => 'sample_id',
    'body' => [
        'name' => 'Sample Product',
        'description' => 'My description...',
        'price' => '3400',
        'stock' => '150',
    ]
];
$response = $client->index($params);
dump($response);

The $response I get is No alive nodes. All the 1 nodes seem to be down. From the dump command above this is request made which is not requesting 9200 (not sure if this is correct or not).
