Default Authentication links does not work

I am following this user manual: http://ift.tt/2lGfRnn written for Laravel 5.4

I first created a new Laravel application by issuing:

$ laravel new mysite

In .env file I changed DB_DATABASE=mysite_db

Then I switched to /Code/mysite directory and issued:

$ php artisan make:auth
$ php artisan migrate

When I point to http://ift.tt/2qxdF3V I get the message: "Sorry, the page you are looking for could not be found." http://mysite.app/login is also the same. I also tried http://ift.tt/2pvoWmT.

Why the default Authentication routing does not work?
