fee_estimate_unavailable

HTTP status: 503. Retrying the same request can succeed.

Why it happens

• Nowgate quotes a payout's network fee from an estimate it refreshes continuously; when the network can't be read, the estimate grows stale and payouts are refused rather than guessed.

What to do

Retry after the Retry-After header's seconds.

Example

The response is application/problem+json. Branch on code, never on title or detail. See errors for the format.
