Hail Knights!
As NTT Game support team, we are aware of the problem which is related with one of the payment methods at portal, Paypal. Currently, users can't complete their Paypal payments due to some technical issues.
In this period, users may prefer to use our other payment methods for their Npoint buying. You can see the other methods in here.
We will update this thread after problem has fixed.

Hello again,
Paypal issue has been resolved. You may charge Npoint through Paypal payment.
