# I'm getting a "Invalid Card Request" error

This error can occur when the customer is using a **\*VPN** or known proxy when making a payment. These are sometimes associated with fraudulent activity, so the transaction was flagged and blocked.

The customer should try to pay from outside the VPN.

**\*VPN** - Virtual Private Network - encrypts data and hides a customer’s IP address. Data center IP / Proxy - also used to hide customer’s IP address
