iPhone 8 plus touch ID not working

I bought my new iPhone 8 plus phone today and set it up and everything as soon as i try to register my touchID it fails, it won’t even read my finger! I have tried clean the button, washed my hands like 4 times nothing seems to work!! Rebooted it and a message comes on saying ‘Phone disabled wait 5 minutes’ why would it do that if it’s a new phone, I’m on IOS 11.1.1
