When a Cloudflare payment fails, your bank might need to remove a hold, you might need to fix outdated billing information, or your account might lack sufficient funds.
The most common reasons why transactions are declined when Cloudflare tries to process your payment are:
Bank placed a hold
The bank or card issuer has placed a hold or other similar measure that prevents Cloudflare from charging the card on file. The email you received alerting you about the failed payment lists the specific reason for the decline.
Contact your bank to check for any restriction that would prevent Cloudflare from successfully processing your payment.
Outdated billing information
The billing information that Cloudflare has on file is inaccurate or incomplete. Also, the credit card on file might have expired.

Cloudflare was unable to collect payment due to insufficient funds in the account on file. Contact your financial institution to ensure fund availability.
