How to view map in top down perspective as client?

Hello, I would like to rotate the camera of the client down, so that the client can see the map from the top down perspective. How can I do that?

This is my map:

Server top down view and client side view (this works fine):

Server side view and client top down view (this does not work):

I found out that the clients camera POSITION is correct, but the ROTATION is wrong. So the client hoveres above the ground and the boxes but does not rotate down to see them.

How can I change the rotation of the client so he can see the ground and the boxes?
