Nvidia Nvenc Locking Me Out

Not sure if this is a hardware (video card) or a software (Nvidia NVENC) question, but here goes. For some reason, the NVENC on my Nvidia GTX 1060 6GB is locking me out of getting above 720p or 30FPS.

For some reason, I can get full 1080p resolution and a smooth 60FPS when previewing inside a program like OBS for example. But as soon as I try to live stream it, it gives me an error saying my NVENC is either unsupported or I need to update my video driver (which I already have recently).

Why is this happening and why won't NVENC cooperate when trying to get to 1080/60 in my settings? If I stay below this, it's fine (this happens on both Facebook Live and YouTube Gaming as well)
