How to Fix the 504 Gateway Timeout Error

1. Retry the web page by selecting the refresh/reload button, pressingF5 , or trying theURL from the address bar again.
   Even though the 504 Gateway Timeout error is reporting an error outside of your control, it might only be temporary.
2. Restart all of your network devices . Temporary problems with your modem,router ,switches , or other networkinghardware could be causing the 504 Gateway Timeout issue you’re seeing. Just restarting these devices could help.
   While the order you turn_off_ these devices isn’t important, the order that you turn them back_on_ is. In general, you want to turn devices on from the outside-in. If you’re not sure what that means, check out the link at the beginning of this step for a complete tutorial.
3. Check the proxy server settings in your browser or application and make sure they’re correct. Incorrect proxy settings can cause 504 errors.
   Most computers don’t have proxy settings at all, so if yours are empty, just skip this step.
   See Proxy.org for an updated, respected list of proxy servers that you can choose from.
4. Change your DNS servers , especially if all the devices on your network are getting the same error. It’s possible that the 504 Gateway Timeout error you’re seeing is caused by an issue with theDNS servers you happen to be using.
   Unless you’ve previously changed them, the DNS servers you have configured right now are probably the ones automatically assigned by yourISP . Others are also available to choose from. See our Free & Public DNS Servers list for options.
5. Contact the website. Website administrators may already be working to fix the root cause of the error, assuming they’re aware of it, but there’s nothing wrong touching base with them.
