Introduction to HTTP Error 403.14 – Forbidden Access

HTTP Error 403.14 occurs when an IIS server is configured to prevent users from accessing a specific page or website. The error message typically states that “The web server is configured to not list the contents of this directory.” This error can be caused by several issues, including incorrect web.config file settings, directory browsing permissions, and URL rewrite module configuration issues.

Understanding the causes of HTTP Error 403.14 – Forbidden Access

There are several reasons why you may encounter HTTP Error 403.14 in Visual Studio 2015. One of the most common causes is an incorrect web.config file setting. The web.config file controls many aspects of your website, including authentication, session state, and caching. If the web.config file is not configured correctly, it can prevent users from accessing your website.

Another cause of HTTP Error 403.14 is incorrect directory browsing permissions. Directory browsing permissions control who can access the files and folders on your website. If these permissions are not set correctly, users may encounter HTTP Error 403.14 when trying to access your website.

Additionally, the URL rewrite module configuration can also cause HTTP Error 403.14. The URL rewrite module is used to rewrite URLs on your website, and if it is not configured correctly, it can prevent users from accessing your website.
