The HTTP 403 Forbidden means that the server understood the request but refuses to process or respond to it. Authorization is not a solution because the resource requested by the client is considered forbidden by the server as you don’t have permission to access it. A server that wishes to specify the reason for forbidding access will display in the response payload.

If the authentication credentials were provided in the request, the server considers them insufficient to permit access. The user should not repeat the request wit the same credentials instead try repeating with new or different credentials. However, the request will be rejected for unrelated credentials. An origin server that wishes to “hide” the current existence of a forbidden target resource can instead respond with a status code of HTTP 404 Not Found.

Reasons for 403 Forbidden Error

Forbidding the directory website for a website os the most common reason for this 403 Status code. Almost all the sites expect you to navigate the site with the URLs in the web pages. They forbid your access to browse the file directory of te site

Fix 403 Forbidden Error

The below steps will help you fix 403 Forbidden Error code.

  1. Firstly confirm if you have encountered a “No directory browsing” issue. Check for the URL if it ends with a slash ‘/’ instead of a web page with a .htm or .html. If this the issue then you have no other option but to access individual web pages of that website.
  2. Make sue that there should be some content in the directory. If not, until any content is added to the home page directory that is assigned by your ISP, a 403 Forbidden message will be thrown to the visitors.
  3. If you have secured your website strong enough, that is not open to the casual internet users, then there are chances of 401 Not Authorised message being displayed.
  4. The 403 Error may also arise if you have once hosted the site but now no longer do so. It will not have any redirection to the new URL. So if you have made any recent changes to your site 403 forbidden is a possibility.
  5. If you are sure that the website should be accessed to all as you have not made any recent changes to the site, then more likely the site could have some deeper problem.
  6. If you don’t have any of these issues but still continue to get a 403 Forbidden code, then it is the web server that disallows certain patterns of HTTP traffic. That is the server allows communications from a well-known browser but not from automated communications which are then rejected using the 403 Error Code.
