Resolve Subscription Payment Failure for claud ai

I’m trying to activate my Claude AI plan but the payment verification keeps failing when I use my credit card. The transaction simply drops without showing any error code or message, so I can’t see where the process is breaking. I’d like someone familiar with subscription platforms and payment gateways to walk through the flow with me, spot the fault, and get the charge to clear successfully.

Please be ready to:
• Review the current checkout and verification steps (card input, 3-D Secure if triggered, fraud checks, etc.).
• Identify whether the failure sits on my side, the card network, or the billing provider’s API.
• Suggest or implement the exact fix—whether that’s adjusting gateway settings, retry logic, or supplying the right verification data—so the subscription activates immediately after payment.

Experience with credit/debit card processors such as Stripe, Braintree, or Adyen is ideal; knowledge of SaaS subscription flows is a bonus. Once payment verifies and the Claude AI account shows as subscribed, I’ll consider the job complete.
