Laravel POST API -> cURL error 28:

Hi all, hope you are all doing well,

on my project, I faced an issue with posting data to an internal API, and keep getting cURL error 28 which means "Operation timed out after 30006 milliseconds with 0 bytes received"

BUT when I test the same API with the same values in POSTMAN it works fine, [Screenshot] -> https://tppr.me/hensp

And my code is attached below.

Thanks in advance

public function addToCart($productId, array $options = [], $quantity = 1)
    {
        $this->product = Product::findOrFail($productId);

        if (!Session::has('cart-token'))
            Session::put('cart-token', Str::random(100));

        $response = Http::post(env('APP_API_URL') . '/cart/store', [
            'productId' => $this->product->id,
            'quantity' => $quantity,
            'options' => $options,
            'cartToken' => Session::get('cart-token')
        ]);

        $this->dispatchBrowserEvent('alert', [
            'type' => $response['status'] ? 'success' : 'error',
            'message' => $response['message']
        ]);
    }

and the env variable is

APP_URL=127.0.0.1:8000
API_VERSION=1
APP_API_URL="${APP_URL}/api/v${API_VERSION}"
