Download link only from the same network
The temporary download link was minted on one network and opened from another. Product text: it can only be used from the same network it was created on.
Why this happens
Link IP logic (link_ip_logic) is not All IPs. At mint the consumer IP fingerprint is stored; at /d/{token} consume the IP must match Exact / first-three / first-two octets. VPN, mobile data, or a different Wi‑Fi often breaks Exact.
Diagnose and fix
1. Visitor: mint and download from the same network, or turn off VPN mid-flow.
2. Admin: Settings → Files → Link IP logic — set to All IPs to disable binding, or use first-two/first-three for softer matching.
3. Distinct from owner Whitelisted IPs and from geo blocks.
4. After changing logic, mint a new link (old grants keep old fingerprints).
