Common Causes of the 404 Error
- Deleted or Moved Pages: If a page has been deleted or moved, the server will return a 404 error when the URL is accessed.
- Typos in URLs: A simple typo in a URL can lead to a 404 error.
- Incorrect Redirects: If a redirect is set up incorrectly, it can lead to a 404 error.
- URLs with Non-existent Paths: Accessing a URL that doesn't exist on the server will result in a 404 error.

Diagnosing and Fixing the 404 Not Found Error on Your Nginx Website
Using Nginx Error Logs
Nginx error logs can provide valuable insights into why a 404 error is occurring. You can access these logs by navigating to /var/log/nginx/error.log on your server.
| Error Log Entry | Description |
|---|---|
| "404 Not Found" | Indicates that a requested resource was not found. |
| "file not found" | Indicates that the server cannot find the file specified in the request. |
| "client requested range not satisfiable" | Indicates that the client requested a range of data that is not available. |
Implementing Redirects
If a page has been moved or deleted, you can implement a redirect to the new location. This can be done by adding a rewrite rule to your Nginx configuration file.
server {
listen 80;
server_name example.com;
location /old-page {
rewrite ^ /new-page permanent;
}
}
Setting Up a Custom 404 Page
A custom 404 page can provide a better user experience and direct users to other relevant pages on your website. You can create a custom 404 page and reference it in your Nginx configuration file.
error_page 404 /custom-404.html;
