When baking occlusion culling, the Near Clipping Plane value needs to be set higher than 0.01 (around 0.2/0.3 seems to works best) or you will get clipping issues when near to walls (i.e. occluders).
Looking at this gate, everything is OK:
Moving head towards the wall, everything is not OK:
If you view in scene view you'll also see the camera is clearly located still inside the room.
So this is what happens when upping Near Clipping Plane to 0.3:
The occlusion issue is fixed but, understandably, if the wall is too close to the camera then you will now see through it.
Setting the capsule colider on Nolan to some ridiculous value does solve both the issues, but then the character can never get anywhere near the walls. I tried playing around with the "Look Offset" and "Look Down Offset" values on the Camera Controller but they seem to make a difference to the issue.
