I just created a new project of laravel version 5.5 with the laravel installer.And run the command \"php artisan make:auth\".The views and controller are generated
This issue is mainly caused because you don't have the csrf token in your form. During csrf token verification it fails, that's why you are getting this page. Laravel generally needs csrf token in all its forms. You can add a csrf token simply by adding this inside the form.
{{ csrf_field() }}
Another method of doing this is you can exclude your route in the verifycsrftoken middleware.
Just add a protected field in the middleware with your route name.
protected $except=[
'1st route',
'2nd route',
.
.
];
This should work.
