To process the failed payment, you can navigate the Billing section of our customer portal and click the green "Retry payment" or "Reactivate account" button (the button displayed depends on whether the account is disabled) on the right side of the page. This action will process the payment of the outstanding balance; additionally, if the account was disabled due to the failed payment, the account will be automatically re-enabled.
