I created a New Minecraft account today, because I wanted to buy the game. When I was done with creation, a link led me to this page: https://my.minecraft.net/de-de/store/minecraft/#login/buy where I should log in with the new account to Minecraft to buy and download. I have entered my new user data (email / password) correctly but when I click on the Login button the following error message is displayed again and again:
OOPS!
Due to an error, your request could not be processed. Please try again.

I have tried again and again. Always the same message.

I would be happy for help.
