Subscription payment failed

[LENVII]

Hello, we have successfully added the credit card in the backend.
However, when adding employees and selecting payment in the subscription employee option, a prompt appears indicating payment failure.
May I ask what is the usual reason for this?
What steps can be taken to check or resolve this issue?
Please find attached a screenshot.
Thank you!
