iPhone refuses to connect to computer

I have this iPhone 8 Plus I’m trying to unlock with iTunes and it does not seem to connect to my computer. My computer’s juice is not the issue as I tried another device and it even supports fast charging! The phone does charge from a power adapter connected to the wall socket but does not charge from the computer. There are also no signs of the computer detecting it. However if powered off it will turn itself on if connected to the computer. Any way of fixing this issue?
