I found it is part of Google Security. A pain but it works.
This page describes how to fix the Google Wallet “Your order was declined because it was considered high-risk” message. The “Error – Your order was declined because it was considered high-risk. Please try again in 30 minutes” automated message is a part of a fraud detection system used by Google and GooglePlay (Google Play, Play Store), including Google Wallet. The fraud detection message usually arrives after a user attempts to make a purchase using Google Wallet and Google payment systems on multiple devices, including Android and Windows smartphones. The attempted payment will be immediately cancelled and in some cases cancelled in a period of allotted days.
For your protection.
