Set the base URL to http://127.0.0.1:38480 and click Save & refresh — the client pulls the Bearer token on loopback (GET /v1/local-token). When cloudflared is installed, the daemon also opens a quick tunnel; the public base URL appears above for other devices (same POST /v1/push paths as CoffeeDrive/ on disk).

Connect above, then push from Coffee Social or run the daemon.
