The 504 Gateway Timeout Error is an HTTP status code that indicates a server failed to receive a response from an upstream server or application within a specific time frame.
This error message is often displayed as “504 Gateway Timeout” or “504 Error” and can be encountered on various websites and web applications.
Understanding the common causes of this error, how to troubleshoot it, and implementing the best practices to avoid it can help minimize disruptions to your online experience. And this article is aimed at satisfying those thoughts.
What are the Possible Causes of 504 Gateway Timeout Error
Several factors can cause the 504 Gateway Timeout Error. One of the most common reasons is a slow server response time or an overloaded server, which occurs when the server cannot handle the incoming traffic.
This could be due to a sudden surge in traffic, poorly optimized code, or insufficient server resources.
Network connectivity issues, such as DNS resolution failure, congestion, or a faulty load balancer, can also lead to the 504 Gateway Timeout Error.
SEO Impacts of the 504 Error Variations
Your computer or website will return the 504 error message when there is a late response or failure of data exchange from another server.
This error can hurt SEO by preventing search engine crawlers from accessing your website and indexing its content.
Here are some of the SEO impacts of the 504 error variations:
Slow Website Speed: The 504 error can occur if your website takes too long to load or respond. Slow website speed can frustrate your customers and will always result in a poor user experience and lower search engine rankings.
Crawl Errors: Search engine crawlers may encounter a 504 error when accessing your website’s pages. This can result in crawl errors and prevent search engines from indexing your content.
Decrease in Search Rankings: If search engines cannot crawl and index your website’s content due to a 504 error, your search rankings may decrease over time. Worse side of it; you lose organic traffic and conversions.
Negative User Experience: A 504 error can lead to a negative user experience for your website’s visitors.
If your website is frequently down or slows to respond, visitors may become frustrated and choose to leave your website, resulting in a higher bounce rate.
HTTP 504 Error Variations
The HTTP 504 error message occurs when a server fails to receive a timely response from another server, typically a proxy or gateway server. Some common variations of the HTTP 504 error message include:

504 Gateway Timeout:
This variation of the HTTP 504 error message is similar to the first one but includes a hyphen in the word “timeout.”

Fixing HTTP Errors on WordPress
Various issues, such as server configuration problems, plugin conflicts, or corrupted files, can cause HTTP errors on WordPress. Here are some steps you can take to troubleshoot and fix HTTP errors on WordPress:
Check For any Recent Changes.
If the error occurred after making any changes to your website, such as installing a plugin or updating WordPress, try reversing those changes to see if it resolves the issue.
Check Your Server Logs
Look at your server logs to see if there are any error messages related to the HTTP error. You can usually find your server logs in your hosting account’s control panel or by contacting your hosting provider.
Increase PHP Memory Limit
Sometimes, HTTP errors occur because your PHP memory limit is too low. Add this code define ( ‘WP_MEMORY_LIMIT,’ ‘256M’ ); to your wp-config.php file.
Try disabling all your plugins to see if a plugin conflict causes the HTTP error. If the error goes away, then reactivate each plugin one by one to determine which one is causing the issue.
Check File Permissions
Ensure that the permissions of your WordPress files and folders are set correctly. You can set the correct permissions using an FTP client or your hosting provider’s file manager.
Sometimes you may be running an outdated version of WordPress, or there’s a problem code in the entire program. A simple action of backing up essential files and reinstalling will do the trick.
If none of these steps work, contacting your hosting provider or a WordPress developer may be best for further assistance.
