4xx Client Error
421
Misdirected Request
The request was directed to a server that cannot produce a response.
What it means
A 421 Misdirected Request response indicates the request was sent to a server that is not able to produce a response, often because of a misconfiguration of the server's authority or routing.
Common causes
- A connection was reused for a request to a server that does not handle that hostname.
- Server routing or HTTPS authority is misconfigured.
How to fix it
- Retry the request on a fresh connection.
- Check server configuration for proper hostname routing.
