1.12.2 Server problem

I Recently set up a server on Aternos.org and added 17 mods, all of them are working except one. The problem with that one is that apparently the packet size of the items is too large:

Help with this would be great, The mod that is doing this is called "[Immersive Vehicles/IV/MTS] VEB Automobilwerke Schwikau Military/Civilian Tanks, Helicopters, Planes, and more!"



You can spawn all of the vehicles but cannot go into the parts tab and put the parts/ammunition for the vehicles in your inventory. The server will disconnect you
