You do not have permission to view this directory or page because of the access control list (ACL) configuration or encryption settings for this resource on the Web server. IIS, Asp.Net

I got following error :

HTTP Error 401.3 - Unauthorized
You do not have permission to view this directory or page because of the access control list (ACL) configuration or encryption settings for this resource on the Web server.

I have tried different solutions such as changing permission on folder, and than changing permission on IIS website to everyone etc...

But nothing works, Finally I have changed in "IIS->Authentication->Edit Anonymous Authentication to Application pool Identity instead of specific user". It worked perfectly.
