416 Range Not Satisfiable

Estimated reading: 2 minutes 716 views

This error code indicates the server cannot provide the requested ranges.

Usually this occurs when the serving document, or file, does not have the values requested. In some cases, the error could be in the Range header value, where it does not make sense to the server.

When this error occurs, browsers will usually abort the request, for example a download request. When the request is not aborted, the client application will re-attempt the request.

If this error is unexpected the user should verify the Range of the request and re-attempt. If the response persists then the user should attempt to contact server support for help.

The HyperText Transfer Protocol (HTTP) 416 Range Not Satisfiable error response code indicates that a server cannot serve the requested ranges. The most likely reason is that the document doesn’t contain such ranges, or that the Range header value, though syntactically correct, doesn’t make sense.

The 416 response message contains a Content-Range indicating an unsatisfied range (that is a '*') followed by a '/' and the current length of the resource. E.g. Content-Range: bytes */12777

Faced with this error, browsers usually either abort the operation (for example, a download will be considered as non-resumable) or ask for the whole document again.
