Hi,
Please wrote those four functions here.
I have a function that called from Animation Blueprint and it’s just only run on client owner and server and not on other client,
I want to know how i can call it on other clients ? I get an error about no owning connection for that function.
This is my code:

.h

UFUNCTION(BlueprintCallable, Category = "Animation")
void EndAttack();

	UFUNCTION(Reliable, Server, WithValidation)
	void ServerEndAttack();
	void ServerEndAttack_Implementation();
	bool ServerEndAttack_Validate();

.cpp

void AMyClass::EndAttack()
{
	
	if (Role < ROLE_Authority)
	{
		ServerEndAttack();
	}
}

void AMyClass::ServerEndAttack_Implementation()
{
	EndAttack();
}

bool AMyClass::ServerEndAttack_Validate()
{
	return true;
}
