The QR poll showed a generic "network error" for any failure, and the server collapsed every upstream failure into an opaque 502 with no log. - Classify upstream failures (DNS, timeout, unreachable, TLS cert, HTTP status, bad response) and return host-specific localized messages. - Report why the post-scan user lookup failed instead of a generic invalid-credentials error. - Log the real errno/message server-side for every qr-proxy failure. - Show the server message in the QR poll UI; keep "network error" only for failed local fetches.
