Iray viewport showing preview with one camera but not another

I know this seems like a very strange question but has anyone had any issues with the Iray preview? It seems that it works with one camera but not the other and all my cameras are on the same settings! It makes trying to render anything rather tricky ...

In case you're wondering, when it doesn't work, all I see is black in the viewport - like there are no lights. However, if I switch to another camera, I see the preview ... Anyone has any ideas?

    Is your camera inside of an object (like a wall) or underground?

    I only experienced the case when the geometry of an object is very closely in front of the camera (i.e. the camera is in fact hidden or partially hidden)... then there's no issue with Texture Shaded but it's all dark with Iray Preview...

    Edit: similarly like barbult mentioned. If that's the case you have, just zoom in a bit with the camera or tweak the camera's position.
