Could not reach the server — check your connection and try again
Premium/checkout client catch when the browser cannot reach the API (premium.serverUnreachable). Mapped from “Could not reach the server…” in checkout client messages.
Why this happens
Offline device, DNS/proxy failure, or aborted request — same family as auth Network error siblings, on the payment UI.
Diagnose and fix
1. Check internet; hard refresh; retry.
2. If Network shows a status/body, follow that payment error instead.
3. Admin: confirm the site and /api/checkout/* are up behind the reverse proxy.
4. Distinct from gateway declines after a successful round-trip.
