How to Fix 500 Internal Server Error NGINX

You may have encountered the 500 internal server error NGINX when trying to visit a website or online service. You could be pondering whether your Internet connection or some other problem is to blame for this error.

It should be emphasised that this 500 error is truly a server-side issue and is not a result of any negligence on your part. Therefore, the server administrator or webmaster needs to rectify this.

Let’s now look at how to resolve NGINX Internal Server Error 500 in this guide’s detailed section.

What is 500 internal server error NGINX?

500 internal server error is a generic error message displayed when an error has occurred on the web server. This can be caused by several things, including problems with the server itself, problems with the website’s code, or even just a simple typo. The error message is pretty unhelpful, but there are ways to figure out what is causing it. If you’re using NGINX, there are some specific steps you can take to troubleshoot the issue.

It simply implies a problem with the website or online service you are attempting to access or visit if you see a 500 Internal Server Error in NGINX.

In this instance, the mistake is ultimately coming from the website’s end and isn’t always an issue with your computer or browser. However, it doesn’t follow that you have no options for resolving the 500 problems on your end.

Error 500 internal server NGINX denotes that a problem prohibited the web server from processing the request because it was unexpected.

This can be the result of a setup error, a broken plugin, or a problem with the server’s software.

Here are a few basic ways that you may see the HTTP 500 blunder:

  • How You Might See a 500 Error
  • 500 Internal Server Error
  • HTTP 500 – Internal Server Error
  • Impermanent Error (500)
  • Inner Server Error
  • HTTP 500 Internal Error
  • 500 Error
  • HTTP Error 500
  • 500. That is a blunder

When a server-side issue stops NGINX from sending a suitable response, NGINX returns a 500 Internal Server Error.

It might be caused by a variety of factors, including a flawed script, missing files that code refers to, insufficient file permissions, etc.

The most frequent cause of the 500 Internal server is a fault in one of NGINX’s web servers, most frequently Apache, which has run into a problem and delivered a 500 error response to NGINX, which is subsequently returned to client browsers.

In NGINX, there are several ways to resolve internal server errors.

How to fix 500 internal server error NGINX?

Below are some tested fixes for 500 Internal Server issues in NGINX that are provided for website visitors and administrators in this article:

Access the website in private mode by Incognito Mode

The browser does not save any cookies or cache for the material you visit when you are in private mode (also known as an incognito mode). You should thus be able to visit the website in private mode or incognito mode if it is a cache-related issue.

Refresh/Reload the Website

Although it may sound absurd, sometimes a mistake is only momentary, and a quick reload or refresh enables you to use the website without any issues.

Therefore, all you have to do to execute a hard refresh or reload of the website or webpage is hit Ctrl + F5 on a PC or Cmd + Shift + R on a Mac. Try the following solution if this doesn’t address the issue.

Apply a VPN

You can try using a VPN and then visiting the website to check whether it works to see whether your ISP (internet service provider) is to blame.

Modify the DNS server

You may just try switching your DNS server if the first two options mentioned don’t work. Either your Windows computer or your router support changing the DNS.

Remove any unused browser extensions

If your browser has a lot of installed extensions, consider uninstalling the ones you don’t use. You can also attempt to do that because sometimes browser add-ons create many issues.

Review the server logs

In a text editor, open the server log so you may examine the most recent queries. Every server log includes details about URL requests as well as the response code for each one.

Identify the queries that cause the 500 internal server error. Only one or a few pages may display this problem while all the others function well.

Identify the requests that result in a 500 internal server error. Open a browser and request the issue URLs after you’ve determined which ones they are.

Check File/Folder Permission

Inappropriate file or folder permissions may also be at blame for this. Have you added or changed any recent files or folders?

Typically, directories require a 755 permission level and file a 644 level. To change file permissions, use FileZilla (Windows) or Chmod (Linux).

You may also review the permissions of other files and folders in your code and make the appropriate updates to your files and folders.

Analyze the Script

The script should then be examined to handle the faulty requests. Is it really there in the appropriate place? In your URL mapping/routing file, are you appropriately referencing it?

Check the file path if your script references another file to be sure it is right. Have you invoked any programmes or functions you’ve referenced properly?

Extend the script timeout

The 500 internal server error may also appear in NGINX if your web server (such as Apache) times out while processing the request. Increase the timeout value on your web server (not NGINX) in these circumstances to maintain its connection with NGINX and provide a suitable response.

The above advice should enable you to resolve the 500 internal server problem in NGINX.

Verify the redirects

Any redirections that have been set up incorrectly in the web server may result in a 500 internal server error. Make sure your mod rewrite module and .htaccess file are correctly set, for instance, if you use Apache as your web server. Check the syntax of the redirection/URL rewriting rules in your server configuration file using a third-party tool as well.


That’s all there is to fixing the NGINX 500 Internal Server Error. There are several problems to be held accountable for, but a poor Internet connection is a typical fault. Nothing has changed for people who claim to have 500 Internal Server Error issues when utilising React apps.
