'The request failed with HTTP status 504: Gateway timeout server response timeout.' I http://pcsupport.about.com/od/findbyerrormessage/a/504error.htm understand 'I think' that this is because the upstream request does not get a response in a timely fashion. But my question is this? How do I change the app.config settings in my win32 application to allow more time to process its data. I assume I require these changes to be made on my app settings as the webservices and IIS hosting the ws are setup with extended times. Look forward to a response and thank you in advance.

The problem is not that your app is impatient and timing out; the problem is that an intermediate proxy is impatient and timing out. "The server, while acting as a gateway or proxy, did not receive a timely response from the upstream server specified by the URI." (http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.5.5) It most likely indicates that the origin server is having some sort of issue, so it's not responding quickly to the forwarded request. Possible solutions, none of which are likely to make you happy: Increase timeout value of the proxy (if it's under your control) Make your request to a different server (if there's another server with the same data) Make your request differently (if possible) such that you are requesting less data at a time Try again once the server is not having issues share|improve this answer edited Apr 11 '13 at 11:22 answered Dec 13 '11 at 19:08 james.garriss 6,03444674 I experienced the same issue, but restarting Apache and Tomcat resolved this issue. Does that mean that the origin server, which I'm assuming is my web server, is too slow processing HTTP requests? –Kevin Meredith Apr 17 '13 at 12:36 3 It means that the origin server (the web server with the data) wa
response. 10.1 Informational 1xx This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line. There are no https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html required headers for this class of status code. Since HTTP/1.0 did not define http://www.getnetgoing.com/HTTP-504.html any 1xx status codes, servers MUST NOT send a 1xx response to an HTTP/1.0 client except under experimental conditions. A client MUST be prepared to accept one or more 1xx status responses prior to a regular response, even if the client does not expect a 100 (Continue) status message. Unexpected 1xx status responses 504 gateway MAY be ignored by a user agent. Proxies MUST forward 1xx responses, unless the connection between the proxy and its client has been closed, or unless the proxy itself requested the generation of the 1xx response. (For example, if a proxy adds a "Expect: 100-continue" field when it forwards a request, then it need not forward the corresponding 100 (Continue) response(s).) 10.1.1 100 Continue The client 504 gateway timeout SHOULD continue with its request. This interim response is used to inform the client that the initial part of the request has been received and has not yet been rejected by the server. The client SHOULD continue by sending the remainder of the request or, if the request has already been completed, ignore this response. The server MUST send a final response after the request has been completed. See section 8.2.3 for detailed discussion of the use and handling of this status code. 10.1.2 101 Switching Protocols The server understands and is willing to comply with the client's request, via the Upgrade message header field (section 14.42), for a change in the application protocol being used on this connection. The server will switch protocols to those defined by the response's Upgrade header field immediately after the empty line which terminates the 101 response. The protocol SHOULD be switched only when it is advantageous to do so. For example, switching to a newer version of HTTP is advantageous over older versions, and switching to a real-time, synchronous protocol might be advantageous when delivering resources that use such features. 10.2 Successful 2xx This class of status code indicates
web browser and a web server that you want to access (e.g. in your ISP) and the gateway experienced a time-out while waiting for a response from either the server that you are trying to access, or from an auxiliary server (e.g. a name server). Outline: Symptoms Cause What you can do about it Extra information Footnotes Symptoms Microsoft Windows Update reports HTTP 504 status codes with error code 0x80244023 (hexadecimal 80244023). Apache servers report this as: Gateway Time-out The proxy server did not receive a timely response from the upstream server. (A footnote2 expands on the meaning of “upstream”) Cause The official description of what causes the HTTP 504 status code is: “The server, while acting as a gateway or proxy, did not receive a timely response from the upstream2 server specified by the URI (e.g. HTTP, FTP, LDAP) or some other auxiliary server (e.g. DNS) it needed to access in attempting to complete the request.” In that description, “URI” can be interpreted as “URL” (Uniform Resource Identifiers that also indicate the Location of the resource), “HTTP, FTP, LDAP” are protocols used for accessing resources, and “DNS” is the Domain Name System that is used to translate names (e.g. www.example.com) into addresses that are used for communication. What you can do about it Try accessing the website through a (different) proxy. If the problem was particular to the gateway/proxy that you accessing the site through, then using a (different) proxy may3 allow you to bypass the earlier gateway/proxy. These errors often arise because the proxy failed to resolve a domain name into an address. It might succeed if you try again, or if you can resolve the name (while the proxy can't, e.g. because it uses different name servers) then you might be able to access the server through its IP address. If the problem is with the website that you are trying to access, then monitor it to determine when it returns to service. Extra information This is the gateway equivalent of the DNS/TCP errors that c
