If you see this error, it means that users cannot access your private site, and it is a message that appears and disappears sometimes. The cause of the problem Most often, a problem (504 gateway timeout) appears when the server cannot connect to a higher server to complete the request, meaning that this problem appears because of your hosting service provider. For example; If you are using a website firewall, such as Sucuri, and you are unable to connect to the WordPress server, you will see a 504 Gateway Timeout error. Sometimes the message may appear to you differently, depending on the hosting company you are dealing with or the browser you are using.
For example: 504 Gateway Timeout HTTP 504 504 ERROR Gateway Timeout (504) HTTP Error 504 – Gateway Timeout Gateway Timeout Error The most common cause of the error is the inability of the proxy server to reach the upstream server. Solution #1: First you have to wait and try again. Sometimes the reason is a temporary glitch in the server you are relying on, and you just have to wait for a while and try again.
Solution #2: Stop VPN Sometimes, your VPN server may not be able to get a response from your managed WordPress hosting server, and this will result in an error. If you use a VPN service to browse the web, try disabling it.
Solution #3: Turn off the website firewall If you are using a firewall for your website (such as Sucuri or Cloudflare), you should try turning off the firewall temporarily, as this will allow you to connect to the server directly. If the problem disappears, this means that the hosting server has blocked the firewall IP addresses that could be causing this problem.
In this case, you should contact your firewall provider to obtain their list of IP addresses, and then contact your hosting provider to whitelist those IP addresses. Solution #4: Disable your Network Proxy If you connect to the Internet through a proxy server, sometimes that server will not be able to get a response from your location.
Try accessing your site using a different Internet connection, or use online services to see if your site is down for you or for everyone. If the site is down only for you, you need to change your network settings.
Solution #5: Change DNS servers
When you use DNS server addresses, this helps your computer connect to different servers on the Internet. If the DNS servers you use are down or unable to connect to your website, You may see a 504 gateway timeout error. Steps to change DNS servers on Windows computers; You can find it under Control Panel » Network and Sharing Center screen on Mac computers; You can find it under Settings » Network, after which you have to click on “Advanced” and choose the DNS tab.
Try visiting your site again, and if this resolves the error, you're all done, the problem was with your internet connection, and it's resolved. Solution #6: Optimize Database A corrupt WordPress database may also cause the same mentioned issue.
