Generally, the failure of payment when purchasing funds is due to the following reasons: 1. The subscription amount exceeds the single one-day limit of the bank card, and the card needs to be changed. 2. The network is overtime or the charging channel is unstable. You can try again later. 3. The bank card is in the status of account cancellation, loss reporting and replacement, and it needs to be replaced. Tips: As the relevant deduction channels of Agricultural Bank and Minsheng Bank have suspended the deduction application, you need to use other banks to purchase funds.
