416 Range Not Satisfiable

The 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 a sense.

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