There are variations of 504 gateway timeout errors like HTTP 504 Gateway Timeout, HTTP 504 Error, HTTP 504, Gateway Timeout (504), 504 Gateway Timeout Nginx, etc.
Basically, the HTTP 504 error occurs due to the following reasons:
- Silent firewall crashes.

- The local network’s proxy server or router is overloaded or crashes.

How to Fix 504 Gateway Timeout Error?
If you encounter the 504 error instead of loading the page, it means there is a server problem on the part of the website provider. Therefore, to fix the gateway timeout error, you can use the following methods:
1. Reload the requested web page
Usually, the error 504 Bad Gateway appears for a while. The easiest solution to fix the 504 gateway timeout error is to refresh the webpage. You can do this by pressing F5 or the Ctrl + R keys. Alternatively, you can enter the URL again.
2. Reset/reboot network devices
When a home network encounters a gateway timeout error, resetting all network devices can fix the problem. There is a chance that the modem and router have been misconfigured, so the HTTP request cannot be carried out.
Additionally, if you encounter an HTTP 504 error on every site you try to access, that is a clear sign that the problem is with the router. You must reset the router to fix the 504 Bad Gateway error message.
3. Check or disable proxy settings
You should check your browser settings if you cannot fix the 504 error after refreshing the page. Usually, if the configuration is wrong or you are using a different proxy, Windows cannot detect the proxy settings.
4. Change DNS server
DNS server helps to connect different servers on the internet. If the DNS server you use is down, you may encounter the 504 Gateway Timeout error. The easiest way to fix this error is to change the DNS server used by the router.
To do this, go to the Control Panel > Network and Sharing Center screen and change the DNS server settings.
On Mac, look for Settings > Network > Advanced button > DNS tab.
After changing the DNS server, now try to visit the website. You should not face the 504 Bad Gateway error.
5. Try again after a while
It may seem too simple, but the 504 error is often not complicated. By simply reloading the web page after a while, you can fix the HTTP 504 error.
6. Try a different browser
Try a different browser if the website works, and you still encounter the 504 gateway timeout error. In addition, you can even try to clear the browser cache and cookies or open it in incognito mode.
7. Flush DNS
Sometimes the 504 error can be due to an incorrect outdated DNS cache. To flush DNS, open the run window by pressing Windows + R.
Here, type cmd, and press Ctrl + Shift + Enter.
It will open Command Prompt in Administrator mode. Next, type ipconfig /flushdns. It will help in fixing the 504 gateway timeout error.
8. Adjust the proxy settings
If you are connected to the internet through a proxy server, the site you are trying to access may not be able to get a response. Therefore, to fix the 504 error, you need to disable the network proxy settings, or you can disable them.
You can also contact your internet service provider to correct the problem.
9. Disable VPN
If you are using a VPN service, try disabling it, as this can be one of the reasons behind the HTTP 504 error. If the error goes away, it means VPN is the culprit. However, if using a VPN is essential, switch to a different VPN.
If nothing worked, try disabling the website firewall, as this can be one of the reasons for the gateway timeout. In addition, you can contact your internet service provider for the solution and check plugins. We hope these steps helped you resolve the error.
