Error 10-0 Activation failed

I tried to install Fortnite and i got the message that the product activation failed. (Activation failed. When processing your request an error has occurred. repeat the process)

I havent found anything about this Error. I tried a lot of things (turn off antivirus, change proxy, create an new account, etc) and at the end I formated my PC and reinstall Win 10 (including all new drivers). But it doesn’t help.

Has anybody an idea?
