Cannot transfer domain to Cloudflare

When trying to transfer domain to Cloudflare I keep seeing “Your payment has been declined. Please check with your payment provider or try again with a different payment method (Code: 1226)” error.

Could you please provide a better description of the error (#1226) so I could call the bank and troubleshoot it ?

From the post linked to below, it sounds like the error message is all Cloudflare can provide. Only your bank knows why the declined the charge.
