Why am I kicked?

I recently wanted to play a round of Fortnite again, but I was prevented from doing so by a kick from the match. The error message attached below appeared. I have no idea where the problem comes from, since I haven't adjusted anything and it always worked before. Please help and hope someone has tips to solve my problem.
Kind regards

Maybe someone else used your account.

The message explains why such a kick can take place. Nobody can know what applies to you here.

In what way? Whenever I tried to play?

Had a high ping?

Internet lag as it says?

Yes, I don't know what applies myself. I have never had any problems with Internet lag, neither my IP nor my system has ever caused problems or has changed recently, I do not use VPN and I do not cheat either. I also have no proxy settings active. The only thing that comes to mind when I get this message is that a Windows update might have something to do with it.

No, never actually

Just restarted the PC and tried again?

Yes

The only thing that comes to mind when I get this message is that a Windows update might have something to do with it.

That could be the cause, Lags.

If you haven't chatted, maybe the problem is with your router. Pull the power plug on your router for 1 minute and then plug it back in and see if the problem still persists after the new connection.

i had 1 to 1 the same problem
