401 Unauthorized loop: - client.ts had no 401 handler, leaving stale expired tokens in localStorage. The PrivateRoute guard only checked token existence, so the app would render but every API call would fail silently. - Fix: on any 401 response, clear the token and redirect to /login. 504 Gateway Timeout on nc-scan: - nginx default proxy_read_timeout is 60s. The scan endpoint makes one Nextcloud request per audio file (list + metadata), which easily exceeds that on larger libraries. - Fix: add a dedicated location block for nc-scan with 300s timeouts. General /api/ block gets explicit 60s timeouts for clarity. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
