Pawn doesn't trigger Box on Overlap

I have a door blueprint with a trigger box which should enable input on overlap with the current pawn. On keyboard input “y” the door should open via rotation. When I set ‘Auto Receive Input’ to player 0 the door while open as soon as I press ‘y’. But if I set it to disabled and the controlled pawn walks into the Box input is not enabled.
I added a OnComponentOverlap → Print String. But the text is not shown as soon as my pawn walks into the box.
Pawn controle is based on the AdvancedTurnBasedTileToolkit but I think that shouldn’t matter…

Also the mouse cursor should change when it is hovered over the door but that doesn’t work either.

Any help would be appreciated!
