## When it happens

The webhook URL points to an internal network address: a private, loopback or link-local IP, or a host name that resolves to one. If any of the addresses a host resolves to is internal, the URL is rejected. A host name that does not resolve yet is accepted.

## How to fix it

Use a public endpoint reachable from the internet. For local development, expose your server through a public tunnel.

## Retry

Not as is: the same request fails the same way. Fix the cause described above, then send the request again, under a new `Idempotency-Key` if the body changed.
