What this error means
XDM requested the file and received an answer it can’t use: an HTTP error status (such as 404 Not Found or 500 Internal Server Error), a response with the wrong size, or a web page where the file should be. Rather than saving an error page under your file’s name, XDM stops and reports the problem.
Typical reasons
- The file was moved or deleted (404). The link on the page is out of date.
- The site needs you to be logged in or to pass a check first. When XDM requests the link without the right cookies, the site returns a login or captcha page.
- The link was copied by hand from a page that builds links with scripts, so the address alone isn’t enough.
- A temporary server fault (500, 502, 503). The server is overloaded.
- The server answered a resumed request differently than the first time, for example a different file size after the file was updated on the server.
How to fix it
- Start the download from the browser instead of pasting the link. With the XDM extension installed, XDM receives the cookies and headers the site expects.
- Sign in to the website in your browser, then download again or use Refresh link on the failed download.
- Check the link in the browser. Right-click the download, choose Copy URL and open it in the browser. If you get an error page there too, the file isn't available.
- Wait and retry for 5xx server errors. Then resume the download in XDM.
- If the file changed on the server, a partially downloaded copy can't be combined with the new version. Delete the download and start it again.
Check the Properties
Right-click the download and open Properties to see the URL, the web page it came from, and the request headers XDM recorded. That's useful when you ask for help on the forum.
