Amazon web services – Access denied when navigate to folders

I upload my html code to S3 and enable the static website option. It works fine only for /index.html

If I navigate to an html file like products/index.html it works fine, but when I navigate to the folder like products/ it fails with AccessDenied.

What is the problem? It should recognise the index.html from inside the folder

        }
    ]
