In this article, we will discuss Error 504, including its causes, solutions, and prevention methods.

What Results in Error 504?

Error 504

There are numerous possible causes for Error 504 to occur. Among the most prevalent causes are:

  • A server can only process a limited number of queries simultaneously. When it is overloaded, it is unable to process all incoming queries, resulting in a timeout.
  • If the upstream server responds slowly to queries, the proxy server may expire before receiving a response.
  • Network Issues Network issues, such as excessive latency or connectivity issues, can prevent the server from retrieving the requested data.
  • DNS Problems DNS servers translate domain names into IP addresses. If DNS issues exist, the proxy server may not be able to locate the upstream server.
  • Issues with the Firewall Firewall configurations can sometimes prevent the server from accessing the requested data, resulting in a timeout.
