416 Range Not Satisfiable
4xx Client Error
RFC 9110
The range you requested doesn't fit within the resource.
What 416 Range Not Satisfiable means {#what}
The client sent a Range header, but the range falls outside the actual size of the resource — like requesting bytes 5000–6000 from a 2KB file. The server responds with a Content-Range header showing the actual size.
When you’ll see a 416 {#when}
- Resuming a download where the local file is already larger than the remote
- Buggy range request implementation
