Fortnite name change is not possible?

I've been wanting to change my fortnite name for a couple of days but it's not happening there, there have been too many resubmissions. Please try again later,

Have you changed that in the last 14 days?

It is only possible to change his name every 14 days, but then another message will come.

I once had this message when I wanted to display the name of a known streamer using other characters (eg alpha instead of a). The characters are per se admissible, but I guess the name and everything that was similar is legally protected.
