Laravel 5.5 Cookie doesn't store

I want to store a custom cookie in user browser and in a register form. I would create an affiliate system.

I test the basic cmd with this:

http://ift.tt/2iJHMFZ

In my controller

    $ref = $request->query('ref');

    $cookie = Cookie('referral', $ref , 60);

    dd($cookie);

The dump of cookie created works perfect. cookie name, value, expire... But nothing is save into user browser. I have used firefox developpment web to check all cookies in browsers.

Browser doesnt store cookie. Why?

Nb: I have used also this package http://ift.tt/2iLGIBI but its the same problem.
