Multiplayer sync pitch

Good day guys. There is a problem, and I want to ask how to solve it as much as possible the right way. Trying to make a melee combat using reykasty with multiplayer support. Needless attack event occurs on the server, and it makes the decision hit\not hit. If you control the listening server, and the other clients see where the attack are applied correctly. But if you manage the client, everyone can see that the attacks are only forward. It is necessary to somehow sync the pitch for the hand mesh, but I do not know how to do it correctly for multiplayer. The picture is not four client, just two cases that I have described. I hope you understand what I mean, my english is very bad. Thank you.
