The new API upload path POSTs to the same cloudatacdn.com nodes as the web
path, so it can hit the same backend flake — a 2xx response with no filecode, or
a transient "no servers available" from /api/upload/server (now that the stale
fallback node is gone). hosters.uploadFile threw GENERIC errors for both, which
the upload-manager would treat as an account failure → mark-failed →
pre-job-swap-blocked on the next batch: the exact symptom 3.3.29 fixed for the
web path, reintroduced via the unprotected API path.
Tag both API-path analogs of the empty form as err.hosterTransient=true:
- codeless 2xx ("lieferte keine file_code-Antwort") — bytes accepted, no link.
- transient "no upload server" (shouldRetryServerLookup true: no-servers/busy/
try-again) — but NOT genuine auth failures (invalid key/unauthorized), which
stay classified as account errors.
The upload-manager checks _isHosterTransientError (flag-based) before the
account-error classifier, so both now fail the file without blacklisting the
account. Consumption side already covered by the 3.3.29 regression test. 173/173.
