What is a 404 Not Found Error?

The 404 Not Found Error is a standard HTTP response status code indicating that the server cannot find the requested resource. This could be due to several reasons, such as a mistyped URL, a deleted or moved file, or a server misconfiguration.

Several factors can contribute to a 404 Not Found Error on your Nginx website. Here are some of the common causes:

• Incorrect URLs: Users might type the URL incorrectly, leading to the 404 error.

• Incorrect Server Configuration: Misconfigurations in Nginx server settings can lead to the 404 error.
• Caching Issues: Cached content can sometimes display outdated URLs or missing resources.
• Search Engine Indexing Issues: Search engines might not have indexed the new URLs correctly, leading to 404 errors.
