What is network request failure 504?

1: Network request failure 504 is what

#504 error is (gateway timeout) The server acts as a gateway or proxy, but does not receive the request from the upstream server in time.

The server (not necessarily a web server) is acting as a gateway or proxy to fulfill requests from clients (such as your browser or our CheckUpDown robot) to access the desired URL. In order to complete your HTTP request, the server contacted an upstream server but did not receive a timely response.

This usually means that the upstream server is down (not responding to the gateway/proxy), rather than that the upstream server and gateway/proxy are inconsistent on the protocol for exchanging data.

2: Network request failed 504 Reason

Normally, it is caused by the requested server sending timeout.

This problem is entirely caused by slow IP communication between back-end computers, possibly including your web server. If your web server is hosted by a website, only the person responsible for setting up that website can resolve this issue.

The use of proxies and caches on the Internet is increasing day by day. Although our CheckUpDown bots will always try to 'get into' the computer that actually hosts your site, where our HTTP requests actually land is not entirely within our control. As long as one link in the chain of computers processing our HTTP requests is broken, errors like 504 can easily occur.

As soon as you encounter a 504 error, please contact the website official (e.g. via email) - this problem cannot be solved personally. The website owner needs to contact the Internet Service Provider (ISP) and Web server software supplier to check the flow of IP data transmission between different computers under their control. However, this error is not easy to solve. Due to the irregular nature of Internet circulation, this type of error is transient.
