Twitch username available or not?

vi

I would like to rename myself on Twitch from JetztMitteLIVE to JetztM1tte.

However, it says "The username JetztM1tte is not available. I thought someone else was already using the name, but when I enter twitch.tv/ JetztM1tte nothing was found.

So why can't I rename myself if the username is "free"?

That said, the guy has never streamed, which is why his channel is not shown to you. These extra URLs must also be requested separately so that you can have the name in there
