How to Replicate Character Movement

Hello, I have bad English, I will translate with the help of an interpreter.

I want to do a check before the player runs.
My game is multiplayer.
I created event Run on server and then made Run on owning client in which function AddMovementInput already worked. Works, but the character while running hangs, possibly due to load. Tell me how to do.
And on mouse turn too please! Need your helps
