Why does it give an error: Operation timed out on POST request?

Question

WordPress

There is a similar code:

require __DIR__ . '/vendor/autoload.php';

use Automattic\WooCommerce\Client;

$woocommerce = new Client(
    'https://example.com', 
    'ck_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX', 
    'cs_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
    [
        'version' => 'wc/v3',
        'query_string_auth' => true
    ]
);

$result = $woocommerce->post('products', [ 'name' => 'Woo Single' ]);
print_r($result);

After its execution, a PHP Fatal error occurs during a POST request: Uncaught Automattic\WooCommerce\HttpClient\HttpClientException: cURL Error: Operation timed out...
But if you access the woo API via get or delete, then the requests are processed correctly:

$result = $woocommerce->get('products');
print_r($result);

Above code will return a list of all products in the store.
The question is why when a POST request is made through a script, timed out occurs.
I tried to create requests to the server through postman, everything works out as it should.

Answer 1

This is a backend question.
It is necessary to look at the implementation of processing incoming POST requests.
Send the server code, let's see what hangs there.
