The billing agreement for the customer's PayPal account was cancelled.
Inform the customer that their PayPal account needs to be added (or re-added) as a saved payment method before it can be used to pay for their Scheduled Order.
If the customer did not intend to cancel their billing agreement, then you can also ask the customer to contact PayPal Customer Service for help with their PayPal account.
If your site offers another payment option than PayPal, you can also contact the customer to have them add a new payment method and add it to their Scheduled Order.
Once a new payment method is added to the Scheduled Order, the Scheduled Order should be processed with the new payment method.
Once this issue is resolved, you should use the action to Restart Processing the Failed Scheduled Order.
