Remote storage disconnecting every time i close the map

[Kpivarias]

First of all sorry for the bad english. I am playing a thorium modpack with my friends, every time i close the world, when i enter again the remote storage disconnect with the storage heart, i dont know if i am doing something wrong or if it is just a bug, also when the remote storage is disconnected and i click to open it, it shows the message but also opens it with no itens inside, when anyone tries to deposit an item inside the game freezes and then we have to quit and re enter.
