Transform bone replication behaves strange

Hey, i try to bend my upperbody via mouse but it doesnt replicate although im multicasting it. How can i solve this?
Server can see clients change.
Client can’t see servers change.

First picture is inside the event graph off my anim bp. It’s triggered by “Event Blueprint Update Animation”. Everything works fine exept the replication.

I’m having the same problem.

Here is a video I made hope it helps.
