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.
Just try like,
http://localhost:8081/paymentclone/public/index.php/authentication/login
