}What is HTTP 416 Range Not Satisfiable?
HTTP 416 Range Not Satisfiable indicates that the server cannot or will not process the request due to something that is perceived to be a client error. This could be malformed request syntax, invalid request message framing, or deceptive request routing.
The client should not repeat the request without modifications.
When Does This Happen?
A 416 Range Not Satisfiable response is returned when:
- The request has invalid syntax or malformed request parameters
- Required parameters are missing from the request
- The request body contains invalid JSON or XML
- Query parameters have invalid values or formats
- The request URL is malformed or contains invalid characters
- Request headers contain invalid or conflicting values
