Light Switch replicated

Hello,

I’m new to Unreal Engine 5, trying to make a light switch that would replicate in multiplayer but can’t get it to work.

Here is the blueprint when the player enters light collision:

Here is the blueprint when the player presses the “E” key to turn the light on or off:

Here is the custom event blueprint (Multicast) :

Unfortunately the light isn’t replicated well in multiplayer, I don’t understand why.

Could someone help me?
