The 504 Gateway Timeout error is an HTTP status code that means that one server did not receive a timely response from another server that it was accessing while attempting to load the web page or fill another request by the browser.
Most of the time, a 504 Gateway Timeout error means that whatever other server is taking so long that it's "timing out," is probably down or not working properly.
Since this error is usually a network error between servers on the internet or an issue with an actual server, the problem probably is not with your computer, device, or internet connection.

** Fixing 504 Errors on Your Own Site **

A lot of times this isn't your fault at all, but it's not the user's either. Start by checking that your server can properly resolve all the domains that your applications require access to.
Very heavy traffic might result in your server serving a 504 error, even though a 503 would probably be a bit more accurate.
In WordPress specifically, 504: Gateway Timeout messages are sometimes due to corrupted databases. Install WP-DBManager and then try the "Repair DB" feature, followed by "Optimize DB," and see if that helps.
Also, make sure your HTACCESS file is correct, especially if you have just reinstalled WordPress.
Finally, consider contacting your hosting company. It's possible that the 504 error that your website is returning is due to an issue on their end that they'll need to resolve.

The 504 Gateway Timeout error may be common, but it’s nothing to be scared of. In some cases, the error might even go away on its own after you try reloading the affected website a few times. If it doesn’t, you may need to get your hands a bit dirty, but it shouldn’t take you long to get your website fixed up.

When you’re ready to troubleshoot the 504 error, here are five ways you can tackle the problem, in order of difficulty:

Check your proxy settings.
Take a look at your domain’s propagation.
