1.
Are you in production? using https?
I had the same problem and was not CSRF token. So I changed AppServiceProvider.php boot() method (which was empty before in my case) for this:
public function boot(UrlGenerator $url)
{
Schema::defaultStringLength(191);
if (env('APP_ENV') !== 'local') {
$url->forceScheme('https');
}
}
Don't forget this line at top:
use Illuminate\Routing\UrlGenerator;
** About using env() outside config files, be sure about executing
php artisan config:clear
Before testing
2.
You need to have write permission to the storage/framework/sessions folder (755)
execute
chmod 755 storage/framework/sessions
chmod 755 bootstrap/cache
chmod 644 vendor (not very sure about this)
SESSION_DOMAIN env variable could be important.

Answer 2

php artisan session:table
Go to env file and change
SESSION_DRIVER=file to ---> SESSION_DRIVER=database
In config directory in session.php file
'driver' => env('SESSION_DRIVER', ‘file') ---> 'driver' =>
env('SESSION_DRIVER', 'database')
php artisan cache:clear
php artisan config:cache
php artisan serve
finish.
