We have a cluster of 2 nodes, when started the cluster, node01 was the leader.
We tested 2 scenarios:
1. node1 is running (it was the leader when started the cluster one month ago), node2 can join successfully.
2. However, after that (both nodes contain the same data), we brought down node1, then try to rejoin it with node2, this test failed, with errors like this:

We had to reboot the cluster eventually, any suggestions why node1 failed to join node2?
