[SOLVED] The Server is not replicating variable to clients

So basically I’ve done everything that was told in the docs: Property Replication | Unreal Engine Documentation

Uproperty declaration:

UPROPERTY(replicated, EditAnywhere, Category = Replication)
bool bReplicatedVar;

In the constructor bReplicates flag is set to true.

AReplicatedActor::AReplicatedActor()
{
 	// 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;

    bReplicates                   = true;

}

And I’ve implemented GetLifetimeReplicatedProps as well.

void AReplicatedActor::GetLifetimeReplicatedProps(TArray< FLifetimeProperty > & OutLifetimeProps) const
{
    Super::GetLifetimeReplicatedProps(OutLifetimeProps);

    DOREPLIFETIME(AReplicatedActor, bReplicatedVar);
}

void AReplicatedActor::Tick(float DeltaTime)
{
	Super::Tick(DeltaTime);

    fDeltaTime += DeltaTime;
    if (fDeltaTime >= 3.0f && Role == ROLE_Authority)
        bReplicatedVar = true;

    DEBUG_U_LOG(FString::SanitizeFloat(fDeltaTime));
    DEBUG_S_LOG(bReplicatedVar ? TEXT("true") : TEXT("false"));
    DEBUG_C_LOG(bReplicatedVar ? TEXT("true") : TEXT("false"));
}

Dont know what is going on and why the property is not replicating. I will appreciate any reply. I’m currently at that point anything is helpful.

Ok, so after reading the documentation once again I have at last figured out that I was missing:

    bAlwaysRelevant = true;

And that’s actually everything that I was missing to get things working. :slight_smile:
Hope It will help somebody in the future!
