That's 2S2P pack which means you need to set the charger for 2 cells...NOT 4. It's the number of cells in series, i.e. 2S, that counts not the total number.

You should measure the pack voltage with a meter and tell us what it is.

If you set your charger to 2S, the charger works with other packs, the charging adapter works with other packs, then your new pack may have a really low voltage cell.

LiPO chargers don't like to see really low cells. They are telling you something is wrong.
