I recently signed up on this website, made an order and I get shown the error in picture below.

Have you tried:

Quote

contacting your bank or your payment provider to get more details about the issue [with your payment]

or

providing an alternative payment method

like it says in that message?

Did you type the full payment details correctly and do you have enough balance in that account?
