According to my personal experience, not all overseas websites support dual-currency cards applied for in China. This is not a problem with your card (as long as the card is dual-currency, you can pay in foreign currency regardless of the currency. Yes, as long as you perform a currency conversion through VISA), or you can open some business, it can be solved. The final analysis is that this website does not support the VISA card of China Construction Bank. When encountering this situation, it is recommended that you call the CCB service hotline first to confirm the authorization status. If it is indeed not authorized successfully and the card status is normal, then contact the other party's website and ask why the transaction failed. If the answer to you is If this card doesn't work, then you can only pay with another credit card (from another bank).
