Connect PC fortnite acc to ps4?

I know how it works. You have to log in to the epic site with the normal epic data and then disconnect with psn

But when I register my new ps4 acc it says that it can only be connected to the old account and not a new one

What can you do there?

Nothing really why do you want a new Ps4 acc?

I watched videos about it and it was said that a ps4 account with which one had not yet played a fortnite would be needed
