Cannot access route apart from the homepage in laravel 5

When i used http://localhost:8081/paymentclone/public/, it showed me the welcome message but when i tried to access my login page http://localhost:8081/paymentclone/public/authentication/login it shows NotFoundHttpException in RouteCollection.php line 145:

and have used it on http://localhost:8000/authentication/login and it works fine.
