When you shut down 3 out of 5 nodes, you lost the ability to have a primary since a majority of nodes must vote for the primary.

When you added a new node, the new node had to sync data from the primary before it could become a new primary. Since there was no primary this sync couldn't have happened.

Your DR plans need to ensure there is always a majority of nodes operational.
