Event not playing for everyone when client triggers it

Pretty much, the game is multiplayer, and i have a matinee play when a player presses the button.

When a client presses it, it only plays for that client, when the host presses it, it plays for everyone. which obviously causes issues, because unless the host presses it too, the client cant got thorught the door (even though its open for them)

How can i set it up so that it plays for the host when anyone presses it, so it plays for everyone else?
(im a UE4 noob, an i havent found anythig that helps so far (thats why im writing this)

There is no connection between the clients, you have to solve it with a client-server architecture:
When someone presses a button, call an event (for example on Player Controller) which is set to “Run on Server”. It’ll then run on the server, and it can execute actions, which will be replicated to all clients (for example opening a door).

I’d suggest reading through the UE4 Network Compendium by eXi, it gives an overall understanding in UE4 networking: http://cedric-neukirchen.net/Downloads/Compendium/UE4_Network_Compendium_by_Cedric_eXi_Neukirchen.pdf

I tried it, and its not working fully, however the custom event set to “run on server” works, thanks!
