A rare chest Spawned in unreachable area

[NationOfDragons]

Me and a friend went hunting for a rare chest and when we got to the location and once there we cleared everything around us and the chest was not around and figured it spawned under bedrock. What can be done about this? coordinates are x:1077 Y:1 z:-771 and was around 10:20 central standard time

Just making sure you are aware, as some new players mix this up - the "distance from chest" refers to the x,z coordinate distance and not the y. The trick is to get to where it says 0 blocks away, and dig down to bedrock from there. If you already knew this and still didn't find it, I suggest just rechecking the same place again as they can be missed by a block or two very easily.
