Dedicated server RPC

Hello.

I’ve tested out some multiplayer stuff with a listen server and it works fine and all. I’m about to test things out with dedicated server. The thing is, I can’t seem to trigger “Run on Server” events. I’m not fully sure on where to put the custom event. I’ve tried game mode (did not work at all, since the server doesnt have the file?). Now I’m trying the game instance, and it does not work either. However, i can print a line from the function and I notice that the “Hello” is coming from Client01, but it is suppose to come from the server.

So the question is: Where should I put the custom events for dedicated servers?
