Xbox controller right stick pulls up when I press down?

Play Fortnite. Have an Xbox One. Push the right stick up, which automatically goes down and the same way around, if I push down, it goes up. Kp what's going on. My controller is new (few months). I didn't touch any settings. Since I plugged in my new headsets, my controller has been crazy. Can't gamble if I can't target my opponents because I swap up and down because it's the opposite.

Check the settings to see if you have accidentally activated reversing of the joysticks, if not you can activate it (then it should work again)!

Does it work normally without a headset?

Where can i find it? That still happens without headsets

Should be in the Fortnite settings. Then go to advanced game setting and then reverse the Y axis

Can't find the game setting for the joysticks.

You're welcome! Actually, advanced options / settings should be in the Fortnite settings below.
However, it may be different in the Xbox version.

On which symbols (see picture above) do you think the game setting would be to change the joysticks? I'm a bit new to xbox and only now play continuously until of course the joysticks are soaking.

How much did you pay?

Fortnite was free with the Game pass Gold Controller has worked until now I just think I unintentionally set something that the x and y axes are mirrored

No, I mean for the console, since you said you were new to Xbox

A friend was able to help. Everything is normal now. Turn around when you have additional game options under Tutorial and Buildings
