### Why VPNs May Prevent File Downloads

1. **IP‑based access controls**\
   When you use a VPN, your real IP is replaced by the VPN server’s IP. Our delivery system only recognizes certain IP ranges, so a VPN address may not be allowed.
2. Shared VPN IPs flagged as high‑risk\
   VPN endpoints are often shared by many users and can be associated with abusive behavior. To protect our service, we block IPs that appear on high‑risk lists.
3. Network routing and DNS conflicts\
   VPNs can reroute traffic or override DNS settings. This can prevent your download request from reaching our servers or block the response from coming back.

**Recommended Solution**

To avoid download failures, please ask customers to disable their VPN before initiating any file download.
