To solve the problem, you should use the following methods:
1. Make the fingerprint of a mobile device or computer unique. Stripe has already noticed your device and marked it as unwanted and dangerous, apparently you have already used another card from the same device. You need to replace all parameters of the device.
2. All system settings of the device must comply with the cardholder's requirements in order not to receive antifraud risk points. The IP address must be as close as possible to the cardholder.
3. The e-mail address must match the name of the cardholder.
4. Try replacing the proxy (socks5) that you used with a dedicated server (RDP), ssh tunnel or VPN provider closest to the cardholder. Check the IP address for cleanliness in spam and black databases.
5. Do not disable the WebRTC parameter in the browser, but replace it with a similar original and unique IP address that you will use as the main one.
6. Do not use an antidetect browser or a virtual machine, and the system should not have any plugins and programs to anonymize the device.
