Do not worry, here we explain what may be causing this error on our website and all the ways to fix it.
What does error 504 mean?
When a visitor enters our website, they make a request via http to our server, which responds by sending the desired content in hypertext form.
This hypertext is interpreted by the browser (Chrome, Firefox …) and displays the page.
The error 504 is caused when it takes too long for our server to process a request.
This is normally due to a failure in the server communication process, which will return an error screen with a code 504 or a Gateway Timeout Error.
Causes of error 504
The 504 error message It appears when an intermediate server between our website and the client’s browser, or a network interface cannot respond to requests from our visitors’ browsers.
These systems transmit communication as links in a chain in such a way that if one stops responding the failure affects the other systems.
There are various causes that can cause failures in these systems. When our local network or our router are overloaded It is common for this error to happen, which will not be limited only when accessing a specific website, but will happen when trying to access any website.
A wrong proxy setting Both client-side and server-side can also cause this error to appear.
You have to look at whether the problem only affects our server or also affects other servers from our provider.
If it affects more sites it is possible that the error is caused by the provider and we will rule out the above causes.
