I think you missed a Server Function.

you ever call a function that is reliable/unreliable, server, withvalidation?

Defined in header like this:

```auto

UFUNCTION(reliable, server, WithValidation) void ServerAction();

```

think this is what you miss.

Actually what you want to do is the same as in the tutorial here.
