HTTP 400. Nothing reached the broker.

**Likely causes:**

- A full name such as Nigeria instead of NG.
- A user-assigned code such as XK, or a typo.

**What to do:** Send an upper or lower case ISO 3166-1 alpha-2 code, for example NG or GB.

**Retry:** No. The same request gets the same answer; change something first.
