Having Trouble with Autofocus

Hi! First post on DPReview! This is because while I've dabbled in photography basically whole life, am just getting really serious about it now, and am still trying to get to know my DSLR camera (the Nikon D750).

As the subject line clearly indicates, one thing I'm struggling with, somewhat surprisingly, I think, is autofocus. I say "somewhat surprisingly" because I thought that this would be something that would make my photography life easier, but so far that's not the case. Specifically, when both my camera and lens are set to AF, sometimes my camera essentially refuses to take the picture when I hold down the shutter button! It's like just nothing happens. Unfortunately, I've missed a few decent shots as a result. The solution is always to just switch both to manual mode, but then, obviously, I have to use the focus ring to focus, myself, which I rather not have to do. So, I would think that the problem has something to do with the camera being unable to find focus while on AF, but why would that be the case?

By the way, in case it makes a difference, I recently switched to Back Button Focus, upon the recommendation of several veteran photographers. But I'm pretty sure this happened even before then.

Thank you!
