If the credit card is available enough, but online payment cannot be made, there are two possible reasons:

First, the trading website has a limit on single payment by credit card, such as Alipay to China Merchants Bank.

2. If the above reasons are not mentioned, it is possible that the accumulated online payment amount set by you for China Merchants Bank's credit card has reached, so you should log in to "Credit Card Online Banking" (the website address is printed on the back of the card), log in to online payment management, and then go to online payment settings to reset the online payment value, or set it to "unlimited", so that you can pay to the credit card cumulatively without being limited by the accumulated online payment amount.
