Rainbow cards too, right?
In addition to the 4 things above, though I don't think it's the same message, it could also be that you're considered outside the party - possibly due to some lag issue. Or the target is too far away. Or just a flat out glitch. QD works fine in Delve for everyone else so just try again next time.
