Experiencing difficulties with payment authorization through a specific platform like Stripe can be frustrating, especially if your card works fine elsewhere. Here are a few steps you can take to troubleshoot and potentially resolve the issue:

1. Check Card Details: Ensure that you've entered the correct card details, including the card number, expiration date, security code (CVV), and billing address. Even small errors can lead to authorization failures.
2. Contact Card Issuer: Reach out to your card issuer (bank or financial institution) to verify that there are no issues on their end. Sometimes, they might have security measures in place that prevent transactions with certain merchants or require authorization for online payments.
3. Check Payment Limits: Confirm that your card doesn't have any transaction limits or restrictions that could prevent the payment from going through. Some banks impose daily or monthly spending limits that might affect online transactions.
4. Try Different Card: If possible, try using a different credit or debit card to see if the issue persists. This can help determine if the problem is specific to your card or account.
5. Clear Browser Cache: Clear your browser cache and cookies or try using a different web browser to rule out any issues related to browser settings or cached data.
6. Contact Stripe Support: If the issue persists, reach out to Stripe support for assistance. They can provide insights into why the authorization is failing and offer guidance on resolving the issue.
7. Alternative Payment Methods: Consider using alternative payment methods supported by the platform, such as PayPal or bank transfers, if available.

By following these steps and troubleshooting the issue systematically, you can hopefully identify the cause of the authorization problem and resolve it effectively.
