Like we said before, this is a data storage issue. You are most likely to face this if you trade items without clearing out your inventory slots. When you trade an item, you receive rublos for it. Rublos is the in-game currency of Escape From Tarkov game. If you don’t keep an empty slot in your inventory, you won’t be able to receive the rublos you were promised on trading your item. This implies a failed transaction. Hence, the transaction would not be processed and the error code 518 will pop up saying that a Backend Error occurred.
