Initially, I provisioned 4 IPFS clusters and it was working as expected. After a month when I created a new node and tried to connect with the existing IPFS cluster, I am unable to connect. Providing cluster peers list as screenshot reference.
In the new IPFS cluster logs, I could see the below errors
DEBUG raft raft/raft.go:284 12D3KooWJKMHUBbZwByPYXd7V8oqCDv5eR6zy8f85YhCfiqTUXMt: get configuration

Raft is mostly legacy at this point, but usually, make sure the new peer is not in the old peerset (peer rm if it is). Re-bootstrap it to it. Verify same secret and connectivity to the others. It would seem the Raft cluster is not committing the new member for some reason. You have to check the logs for the other peers, particularly for the Raft leader.
