504 Gateway Timeout Error – what it means and how to fix it

You may encounter a 504 Gateway Timeout Error. When you open a web page, it’s one of the most common error codes you could get when a website fails to load. If it just appears on one website, you can easily shrug and head to another one. It can be nerve-wracking if it appears on other websites!

Fortunately, this article will show you how to fix it!

First, let’s talk about what a 504 Gateway Timeout Error means. After that, I will cover the potential reasons why a specific website may have this problem. Next, I will explain how you could try and fix this issue on your end. If you own a website with a 504 error, stick around as I will explain how you could resolve it too.

What is a 504 Gateway Timeout Error?

To understand what this error code means, we will have to be clear on how your web browser accesses websites. Here’s how it works:

1. Your server sends a request to another one called an upstream server that hosts that site.
2. Then, the upstream server receives that request.
3. After that, it will respond by providing the resources needed to load the website on your browser.

The 504 Gateway Timeout Error indicates that your server did not respond promptly from the upstream server. The request is timed out, and your server can’t serve as a gateway for that website.

Meanwhile, the “504” is just one of many in the Hypertext Transfer Protocol (HTTP) status codes list. HTTP error 504 is a web server’s way of describing a particular issue.

You may encounter this type of error on any networking device, web browser, and operating system. However, they may use different names for a 504 Gateway Timeout Error, such as:

• Gateway Timeout Error
• Gateway Timeout (504)
• HTTP 504
• HTTP Error 504 – Gateway Timeout
• 504 Error
• 504 Gateway Timeout

What’s more, it might show a longer error message along with these phrases, such as, “The proxy server did not receive a timely response from the upstream server.”

What causes a 504 Gateway Timeout Error?

Different names could describe a 504 error, but they don’t tell you the specific cause of the problem. Here are some of the potential issues:

• Server connectivity – Most websites need multiple servers or third-party hosting providers to host them. If they are inactive or under maintenance, visitors to your website may see the 504 error page instead.
• DNS Changes – The acronym stands for “Domain Name System,” It allows web browsers to look up the right website a web browser wants to access. If you change servers or IP addresses, your website’s DNS server will apply changes for a few hours. Until then, people visiting your site will likely encounter the 504 error.
• Incorrect Firewall Configuration – Your website has a firewall that keeps out hackers or distributed denial-of-service (DDoS) attacks. If you don’t place the correct settings, your firewall might stop visitors to your website. As a result, those folks get a 504 Gateway Timeout Error.
• Network Connectivity Issues – If you’re the only one seeing the 504, then the issue might have something to do with your modem, router, or internet connection.
• Website Coding Errors – Your website’s code might have errors causing errors.

5. You might want to contact your hosting provider or internet service provider. They could check if it’s a problem with the website or something more technical like a DNS issue.
