The reason for "the system is busy, please try again later" when paying.

1. The current network is temporarily unstable. You can switch the network environment or refresh the webpage.

2. Exceeding the payment limit: it not only meets the limit displayed on the Alipay cashier page, but also meets the limit set by your bank card when you apply for a card at the bank.

3. Abnormal bank card status: the bank card may have insufficient balance, cancellation, freezing, password locking, etc.

4. The total amount payable is inconsistent with the actual total amount paid: verify whether the seller has modified the price and refresh the page to pay.

The solution is as follows:

1, first open the mobile phone Alipay.

2. Click on the lower right corner-Mine.

3, and then click on the upper right corner-Settings.

4. Open payment settings.

5. Select-Deduction Order.

6. Select a debit method, and the up and down arrows will appear behind the Android phone. Just adjust the order. Apple's mobile phone can directly drag the "three" adjustments behind.
