and a server that you are trying to access, received an invalid response from another server that it needed to access (e.g. the website that you are trying to access) in order to fulfill your request. For example, the website that you are trying to access may use a gateway to forward your request to other programs, and if such a program gives an improperly formatted response then the gateway would respond with a HTTP 502 error. Outline: Symptoms Cause What you can do about it Extra information Footnotes Symptoms Microsoft Windows Update reports HTTP 502 errors with error code 0x80244021 (hexadecimal 80244021). Apache servers report this as: Bad Gateway The proxy server received an invalid response from an upstream server. (A footnote2 expands on the meaning of “upstream”) Microsoft IIS web servers may report this as “502 - Web server received an invalid response while acting as a gateway or proxy.” and may provide the following extended codes that give a more specific reason of the error: Extended code Reason Description 502.1 CGI application timeout. See Microsoft Knowledge Base article 942059: “Error message when you visit a Web site that is hosted on IIS 7.0: “HTTP Error 502.1 - Bad Gateway”” A HTTP 504 error would seem more appropriate for reporting timeouts, since HTTP 502 errors are intended to report invalid responses. 502.2 Error in CGI application. See Microsoft Knowledge Base article 942057: “Error message when you visit a Web site that is hosted on IIS 7.0: “HTTP Error 502.2 - Bad Gateway”” IIS web servers may also report “The specified CGI application misbehaved by not returning a complete set of HTTP headers.” See Microsoft Knowledge Base article 145661 for details. When Twitter is over capacity, it uses a HTTP 502 response to send its “fail whale” error message: Google servers sometimes report “502 Server Error: The server encountered a temporary error and could not complete your request.”, e.g.: Cause The official description of what causes HTTP 502 errors is “The server, while acting as a gateway or proxy, received an invalid response from the upstream2 server it accessed in attempting to fulfill the request.” Unfortunately, the error does not necessarily indicate what was requested, from which “upstream” server, and what the invalid response was. In the context of Microsoft ISA Servers: Microsoft Knowledge Base article 938465: “Error message when you try to access Web sites through a downstream server af
