What causes the 504 Gateway Timeout error

HTTP 504 error code may be caused by the following reasons:

• The web server is overloaded. The website traffic is too high, causing the server to slowly respond to browser requests, causing other servers to time out.
• Server downtime. This possibility should be considered if almost all users suddenly have HTTP 504 error codes.
• Network settings are incorrect. For example, proxy settings errors, router settings errors, firewall settings errors, etc.
• Other server errors. For example, the website's DNS server has been changed and the website is subject to spam, bots, or DDoS attacks.

How to fix 504 Gateway Timeout error

If you are just a normal user who encounters HTTP 504 error code, you can try the following methods to resolve the issue:

• Press the F5 key on a Windows computer or the Cmd R key combination on macOS to refresh the web page. This method may work if the server is temporarily overloaded.
• Use the website downtime check tool to check whether the server is downtime.
• Restart the router or computer.
• If you browse the Internet through a proxy server, the proxy service may change the IP address of your computer to hide your original location, or encrypt your web requests to prevent snooping. If necessary, you can go to Windows Settings > Network and Internet > Proxy to disable proxy settings.
• Flush the DNS cache by executing the command " ipconfig /flushdns " in the command prompt. If the website's DNS server has been changed, this method may eliminate the 504 error code.
• Contact your ISP to see if there are any connection problems on its end.
• Contact the website to see if there are any problems on the server side.

If you are a website owner, the 504 Gateway Timeout error on the website can reduce site traffic and affect your SEO ranking. Fortunately, you can try the following methods to resolve this issue:

• When migrating a website to another Web server, you need to change the domain's DNS records accordingly.
• The CDN service may cause a 504 Gateway Timeout error. To check this, insert a line " your-hostin-server-IP yourdomain.com www.yourdomain.com " into your host file, instructing your computer to load the site from the original server. Then, if the site loads normally, you can confirm this. Then, temporarily bypassing or disabling the CDN may resolve the error.
• Checking the server log can help you identify the culprit of 504 errors. This can help you solve the problem more easily.
• If the HTTP 504 error code is caused by a malicious bot crawling your site at an excessively high rate, you can prevent these violating IPs from accessing your site.
• Popular WordPress websites and online stores often experience 504 errors frequently. You can resolve issues by switching to faster connections, disabling WordPress firewall, checking site .htaccess, and more.
