No Actor reflections

I’ve just (like last week) started to learn UE4, which I would like to use as a render engine… I’ve watched a number of tutorials already, and startd to put some test scenes together…
On this one I don’t understand why the Robot isn’t casting a reflection on the ground? I have aBoxReflectionCapture, that seems to work fine with the environment, a PostProcessVolume with ScreenSpaceReflections enabled… Am I missing something?
Thanks in advance
