403
403 is the code for Forbidden.

Forbidden
HTTP status code 403, a Forbidden error, is a client-side error indicating that the server understood the request but refused to authorize it. In other words, the server says that the client cannot access the requested resource, even though the server knows what resource the client is requesting. Some common reasons for a 403 Forbidden error include:
- Permissions: The user may not have the necessary permissions to access the requested resource. This could be due to incorrect file or directory permissions on the server.
- Authorization: The server may require the user to authenticate themselves before granting access to the resource. If the user fails to provide valid credentials or if their credentials don’t have the required permissions, a 403 error can occur.
- IP address blocking: The server may be configured to block requests from certain IP addresses or ranges, resulting in a 403 error for clients from those addresses.
- Filesystem permissions: If the requested resource is a file or directory on the server’s filesystem, the server process may not have the necessary permissions to read or access that resource.
- .htaccess restrictions: A 403 error can occur on Apache web servers if the requested resource is restricted by directives in a .htaccess file.
To resolve a 403 Forbidden error, you can try the following:
- Check the URL for typos or errors.
- Verify that you have the necessary permissions to access the resource.
- If prompted, provide valid authentication credentials.
- Contact the website administrator or server owner for assistance if the error persists.
It’s important to note that a 403 error is different from a 404 “Not Found” error, which indicates that the requested resource could not be found on the server. A 403 error specifically means that the resource exists, but the client is not authorized to access it.
