HTTP 416 Range Not Satisfiable Error - Meaning & Fix
The HTTP 416 Range Not Satisfiable error occurs when the server cannot provide the requested data range. This typically happens if the range does not exist within the document. The server response includes a Content-Range header showing an unsatisfied range.
Main causes
The requested byte range is not available within the current scope of the document.
The Range header in the request is syntactically correct but logically incorrect or out of bounds.
The file requested has been modified, making previously valid ranges invalid.
The server configuration or settings do not support byte-range requests.
# Request example curl -X POST https://sandbox.oxylabs.io/ -H 'Accept: text/html' -H 'Accept-Encoding: gzip, deflate' -H 'User-Agent: Safari/537.36'
