signing_failed

The snapshot exists but a download URL could not be signed.

What it means: The bulk snapshot is present; the short-lived download link could not be produced.
What to do: Retry later.
Retry: Retry later; the request was sound. Every 503 carries Retry-After with the minimum wait.
Who changes what: Veridion. The request was sound; something on our side did not answer within its budget or failed a check. The API returned nothing rather than something partial.
On the wire: Content-Type: application/problem+json
{"type":"https://www.veridionmarkets.com/data-api/problems/signing_failed","code":"signing_failed","status":503,…,"request_id":"…"}
