This key may not be used from this IP address

Code

HTTP status
403
Where you see it
An error answer (application/problem+json)

How to fix it

Tip

The key has an IP allowlist (set per key in your panel: Developers, IP allowlist) and the call came from an address that is not on it; the detail names that address. Call from one of your listed servers, or add the address (or its range) to the key's list. A key with an empty list works from any IP. Test and live keys have their own lists.

What the answer looks like

Every error is application/problem+json (RFC 9457). Read the code, not the title or detail text, which may change. Keep the request_id when you contact support.
