I always get kicked out of Fortnite rounds. Why?

As soon as I go into a round in Fortnite and jump off the bus, I get kicked for using VPN or something, although I don't use any. Do I have an HWID ban? Others say that you won't be able to get into FN with it, but I can.

How did you come up with an HWID ban? Did you hack

Just contact the support.

I get it because according to my error message it is a ban. So that's what it says on the internet. And I can't play with any Acc, so I think it's an HWID Ban.
Best wishes
