Execute Dedicated Server function from player character

Disclaimer: I’m an unreal noob. Thanks in advance for any help!

I have a project that is coming together nicely, but I’m stuck again.

Dedicated server - working

Clients connect and authenticate - working

Map changes and clients follow - working

Pickup item on level to win the game - problem. Not calling the server function.

I built my pickup item based on the coin tutorial video.

In this case, the server knows about the pickup item, and I see the BP debug messages in my server console. I just want the server to execute a function.

MMDEMO1Character.h

	UFUNCTION(BlueprintCallable, Category = "LEET", Server, Reliable, WithValidation)
		void GetWinnerInfo( const int32& playerID);

	UFUNCTION(BlueprintCallable, Category = "LEET", Client, Reliable)
		void SendWinnerInfo(const int32& playerID);

MMDEMO1Character.cpp

void AMMDEMO1Character::GetWinnerInfo_Implementation(const int& playerID)
{
	UE_LOG(LogTemp, Log, TEXT("[LEET] AMMDEMO1Character GetWinnerInfo"));

	SendWinnerInfo( playerID);

	UMyGameInstance* TheGameInstance = Cast<UMyGameInstance>(GetWorld()->GetGameInstance());
	//TheGameInstance->AuthorizePlayer(PlatformID, MatchKey, playerID);

}

bool AMMDEMO1Character::GetWinnerInfo_Validate(const int32& playerID)
{
	UE_LOG(LogTemp, Log, TEXT("[LEET] AMMDEMO1Character::GetWinnerInfo_Validate Validate"));
	return true;
}

void AMMDEMO1Character::SendWinnerInfo_Implementation(const int32& playerID)
{
	// do stuff on client here
	UE_LOG(LogTemp, Log, TEXT("[LEET] AMMDEMO1Character::SendWinnerInfo_Implementation"));
}
