apple store can't purchase

All day today trying to purchase an app from the Applestore after clicking "Buy", I enter in a loop where I'm constantly asked to confirm my password

Eventually i message requests me to validate my purchase infos

clicking the button an empty blanc page opens up in the app and I read

Your request produced an error.

[newNullResponse]

Checking my infos everything is perfectly in order

Is anyone aware of this porblem in the Applestore?
