Camera LineTrace always goes to same point in the sky

I don’t understand why the end location for my line trace is always the same position in the world. The start location updates, but the end is always the same spot no matter where you move.

Line Trace

	FVector Start = PlayerCamera->GetComponentLocation();
	FVector End = PlayerCamera->GetComponentLocation().ForwardVector + 1500.f;
	FCollisionQueryParams Params;
	Params.AddIgnoredActor(this);
	DrawDebugLine(GetWorld(), Start, End, FColor(255, 0, 0, 1), true, 10.f, 2, 20);
	return GetWorld()->LineTraceSingleByChannel(Hit, Start, End, ECollisionChannel::ECC_Camera, Params);

Try:

FVector End = PlayerCamera->GetForwardVector() * 1500.f + Start;

Changing it to * made it lower but it is still always in the same position.

Well it works when you first spawn in, but when you rotate eventually it starts line tracing in a random direction?
