Nginx 500 Internal Server Error

Nginx 500 Internal Server Error. Due to a variety of factors, the NGINX server may occasionally return a 500 Internal Server Error. This post will explain what 500 Internal Server Error in NGINX means and how to fix 500 Internal Server Error.

Nginx 500 Internal Server Error

NGINX is open-source software that is used for web serving, reverse proxying, caching, load balancing, and other purposes. It began as a web server optimised for performance and stability. A common issue that prevents it from sending a valid answer is the 500 Internal Server Error. This kind of error can occur as a result of a bad script or missing files referenced by code.

Because NGINX is a reverse proxy server, one of the most common causes of the 500 Internal Server Error could be one of its web servers, such as Apache. Continue reading to learn more about this mistake and how to fix it quickly.

What does the 500 Internal Server Error mean?

The 500 Internal Server Response code means that the website encountered an unforeseen situation that prevented it from completing the request this evening. It’s a catch-all response that indicates that the server was unable to identify a better error code in response. This error code is a very general HTTP status code on the website server, although it does not accurately represent the problem.

How to Fix Nginx 500 Internal Server Error

1. Reload the web page

This error can arise as a result of a momentary malfunction with the webserver. Reloading the page may help in this scenario. Reload the page using F5 or CTRL + R and see if the NGINX 500 Internal Server Error localhost notice goes away.

2. Check redirections

If you have mistakenly configured any redirections in your web server, you may receive a 500 internal server error. If you use Apache, for example, ensure that the mod rewrite module and the .htaccess file are properly configured.

Check the syntax of redirection/URL rewriting rules in your server configuration file with a third-party tool as well.

3. Check File/Folder Permission

This can potentially be caused by incorrect file/folder permissions. Have you recently added or modified any files or folders?

Typically, files require 644 permission, whereas folders require 755 permission. To change file permissions, use FileZilla (Windows) or Chmod (Linux).

You can also examine the permissions of other files and directories in your code and alter them as needed for your files/folders.

4. Increase Script Timeout

You may also receive a 500 internal server error in NGINX if your web server (for example, Apache) times out on the request. In such instances, increase the timeout setting of your web server (not NGINX) so that it stays connected to NGINX longer and returns a suitable response.

Hopefully, the tips above will assist you in resolving the 500 internal server problem with NGINX.
