[Replicating Actors] Actors doesn't exist on client side

I have a problems, on a c++ first person project.
'm spawning some actors on the server side, those actors are replicated (SetReplicate true) but on the client side they dont exist.
Anyone know why thoses actors don’t exist on client side ?

My Spawned Actor

    // Set this actor to call Tick() every frame.  You can turn this off to improve performance if you don't need it.
    PrimaryActorTick.bCanEverTick = true;

// Called when the game starts or when spawned
void AChunk::BeginPlay()

// Called every frame
void AChunk::Tick(float DeltaTime)
    if (!HasAuthority()) {
            UE_LOG(LogTemp, Warning, TEXT("This chunk exist on Client Side"));

I’ve also try to replicate an array of those actors but this array was replicated with nullptr.

Thx in advance for any help.
