Why can't I download youtube on my phone

So I'm using a LG and today my youtube app got deleted so I tried downloading it again but every time I tried to download something would pop up and say sorry unable to download youtube but all the other apps downloaded perfectly it would be nice if someone could tell me why this is happening.

What do you mean by “got deleted”?

Welcome to Android Central! Which LG phone? Did the YouTube icon disappear from the homescreen only, or is it also gone from your App Drawer?
