RU-2001: Too many failed authentication attempts

Your address sent too many requests that failed authentication in a short window, so realuptime stopped checking keys from it for a minute. Successful, authenticated traffic is never counted here.

On the wire

Ships with HTTP status 429, carrying "code": "RU-2001" in the response body alongside the human-readable error message. Existing fields are never replaced by the code: it is additive.

Common causes

  • A client retrying in a tight loop with a bad or missing key.
  • A misconfigured deployment where many instances share one broken credential.

How to fix it

  1. Stop the retry loop first: retrying does not clear the limit.
  2. Fix the credential (see RU-1001 and RU-1002), wait a minute, then resume.

Ask support and mention RU-2001: the code pins down the exact refusal path, so you skip the diagnostic back-and-forth.
