How can I activate shadows?

I just started with armory and now want the objects to cast shadows on other objects.
In the viewport, I see shadows, in the game I don’t. EEVEE or Cycles make no difference. Please tell me, what settings in “Renderer - Shadows” are useful. What else can be my mistake? Where can I look?
Thanks in advance for your answer!

Thank you so much!
I didn’t find a solution so I started from scratch. And now I see shadows!
