Answer

I found a solution for this problem, for fix the problem you should put * in TrustProxies Middleware

like this:

class TrustProxies extends Middleware
{
    /**
     * The trusted proxies for this application.
     *
     * @var array|string
     */
    protected $proxies = '*';

    /**
     * The headers that should be used to detect proxies.
     *
     * @var int
     */
    protected $headers = Request::HEADER_X_FORWARDED_ALL;

}
