Some search engines, like Yahoo and Google, use automated processes to detect soft 404s. Soft 404s are problematic for automated methods of discovering whether a link is broken. The term "soft 404" was introduced in 2004 by Ziv Bar-Yossef et al. Some websites report a "not found" error by returning a standard web page with a "200 OK" response code, falsely reporting that the page loaded properly this is known as a soft 404. A 404 error indicates that the server itself was found, but that the server was not able to retrieve the requested page. Because these two options require special server configuration, most websites do not make use of them.Ĥ04 errors should not be confused with DNS errors, which appear when the given URL refers to a server name that does not exist. In the first case, it is better to employ URL mapping or URL redirection by returning a 301 Moved Permanently response, which can be configured in most server configuration files, or through URL rewriting in the second case, a 410 Gone should be returned.

#Server 404 not found code
The HTTP specification suggests the phrase "Not Found" and many web servers by default issue an HTML page that includes both the 404 code and the "Not Found" phrase.Ī 404 error is often returned when pages have been moved or deleted. At the HTTP level, a 404 response code is followed by a human-readable "reason phrase". HTTP's use of three-digit codes is similar to the use of such codes in earlier protocols such as FTP and NNTP. The following two digits indicate the specific error encountered. In code 404, the first digit indicates a client error, such as a mistyped Uniform Resource Locator (URL). When communicating via HTTP, a server is required to respond to a request, such as a web browser request for a web page, with a numeric response code and an optional, mandatory, or disallowed (based upon the status code) message.

The **ONLY** way a downstream server wants to download a *FILE* from an upstream

If this is a Configuration Manager environment, then my question would be this: Why is a downstream server trying to download *FILES* from an upstream server in the first place. We are managing the updates and computers through SCCM 2012 R2 and not deleting or approving any updates in WSUS.ĭoesn't really matter! A *FILE* that is expected to be present and downloadable is NOT. The views expressed on this post are mine and do not necessarily reflect the views of SolarWinds.

If this is happening on a DOWNSTREAM server it's because something/someone deleted the files from the upstream server. Almost always this involves approvals of *EXPIRED* updates (which have been pulled from the catalog and cannot be downloaded). If this is happening on an UPSTREAM server it is because you have approved updates that are no longer available from Microsoft. The server is failing to download some updates. But i could see the synchronization has completed successfully. Reason: HTTP status 404: The requested URL does not exist on the server. I am getting this error in most of our WSUS servers.
