We’ve detailed exactly what the 504 Gateway Timeout Error is and its most common solutions to help you fix the problem.
What exactly is Gateway timeout error 504?
504 is basically a Hypertext Transfer Protocol status code. That is, it’s a HTTP response code. If the 504 Gateway Timeout Error occurs while your web server is attempting to load a webpage or responding to another request, it means another server upstream has not responded in a timely manner. It means that your web servers aren’t communicating with each other quickly enough.
Hence, rather than loading the website, the browser will display an error message.
The message that appears can vary depending on which browser is experiencing the error.
There are a few ways websites can display a gateway timeout error, but these are the most common:
- This page isn’t working! HTTP error 504

- There is an error 504 Gateway Timeout
- A 504-error occurred
- HTTP 504
- Gateway timeout HTTP 504
- An HTTP 504 error has occurred
- Gateway timeout error
504 Errors and their causes:
Whenever a HTTP response status code falls into the 5xx category, it is defined as a server-side error response. Fives HTTP response code are specified under 5xx category namely error 500-Internal Server error, error 501-Not Implemented error, error 502-Bad Gateway error, error 503-Service Unavailable error & error 504-Gateway Timeout error. That means, if any error of 5xx category occurs, then client solely have any role to play in it. There are 99% chances that it is the shortcoming of server not the client. Simply saying, there is no resource available on the server to support your request.
If you receive a 504 Gateway Timeout error, it means that the web server was not able to get a response on time from another server. Further simplifying the issue, this error occurs when multiple servers are involved in the request. As a result, the first server (typically the main server) times out, awaiting a response from the second server (upstream server). Other servers may or may not be the external one like CDNs, API gateways, etc. In addition, this entity can also take the form of a server within the main web server (e.g., a reverse proxy server, database server).
It’s likely that the problem is not with your computer, device, or internet connection since this error is usually a network issue between two servers on the internet or a problem with a real server on the internet. Similar to the 502 Bad Gateway error, the 504 Gateway Timeout error indicates that a result of an invalid response by the second server (upstream server). This error does not necessarily mean it is temporary as there are multiple reasons for it. During a brief period of downtime, the spiders will try to serve the page from their cache if they are trying to crawl your website multiple times a minute. Even if they did, they wouldn’t notice.
You should fix the 504 error as soon as possible if your site is down for six hours or more. Your SEO can be negatively affected by this.
