The not found Nginx error: causes and solutions

Nginx (pronounced "engin-ex") is an open source web server and proxy server that is designed to provide high performance, reliability and scalability. It is one of the most popular web application servers today. Often, while working with it, you can find the 404 not found Nginx message. Next, we will tell you what this means and how to deal with this error.

What does 404 not found Nginx mean?

The 404 Not Found error of the Nginx web server means that the requested resource was not found on the server. The 404 code is a standard HTTP code that indicates the absence of a page or file that was requested by the user.

Nginx is an open source web server and proxy server that is widely used for static file maintenance, load balancing, caching, and other tasks. When a user makes a request to the Nginx server, it checks for the requested resource and sends the appropriate response.
Causes of the 404 not found Nginx error

The reasons may be as follows:

1. The URL is incorrect: if you entered the wrong URL in the browser's address bar, the server will not be able to find the requested resource.
2. Deleting or moving a file: when a file has been deleted or moved on the server and the link to it remains active, the server will not be able to find this file and will return error 404.
3. Incorrect server configuration: incorrect configuration of the Nginx server may result in error 404. For example, if the path to the requested resource is specified incorrectly in the server configuration file.
4. Resource access restriction: If access to the requested resource is denied to the user or IP address, the server may return a 404 error.
