Ender Chest In Nether and Overworld?

[ShoeLace1291]

I am trying to set up an infinite lava farm in the nether to send lava to my geothermal generator in the Overworld. I am using two ender chests: one in the overworld and one in the nether. both use the same color combo. I have a dimensional anchor in the nether right next to the ender chest there. When I am in the nether, the chest shows that it has one lava bucket in it. When I am in the Overworld, the chest has nothing. I am in a multiplayer server, so the anchor should keep the enderchest loaded, right? What could be the problem?
