The 504 Gateway Timeout error is an HTTP status code that denotes a server that was accessing another server in order to load a webpage or fulfil another request from the web browser but did not receive a timely response from that server. To put it another way, 504 errors typically mean that a different computer that the website you are visiting relies on but that it does not control isn’t communicating with it quickly enough. When a web server encounters a 504 Gateway Timeout error, it means that the information it requested from another server did not arrive in a timely manner. It is known as a 504 error because the web server uses that HTTP status code to identify that particular error type.
