You were removed from the match due to your ip vpn machine or cheating fortnite?

I have a problem,

if I start a Fortnite round and wait 1 minute, I get kicked and the message appears: you were removed from the match due to your ip vpn machine or cheating fortnite.

And I don't have a VPN server on, and I've never cheated. (Except in Creative Destructions)

What can I do.

I would just reconnect the connection to the ISP so that you can get a new IP.
