No owning connection for actor. Function will not be processed.

I solved it by making the Interact() function check for authority, not the PlayerInput()

AMyCharacter.cpp


void AMyCharacter::Server_Interact_Implementation()
{
    Interact();
}

void AMyCharacter::Interact()
{
    if (HasAuthority())
    {
*       [bla bla bla]*

        if (GetWorld()->LineTraceSingleByObjectType(
            OutHit,
            Start,
            End,
            FCollisionObjectQueryParams(ECollisionChannel::ECC_WorldStatic),
            TraceParams))
        {
            AActor* HitActor = OutHit.GetActor();

            ABaseElement* HitElement = Cast<ABaseElement>(HitActor);

            if (HitElement)
            {
**                HitElement->PlayerInput();**
            }
        }
    }
    else
    {
        Server_Interact();
    }
}

ABaseElement.cpp


void ABaseElement::PlayerInput()
{
*   [bla bla bla]*
}
