Cluster does not resume normal operation after Recovery mode

[webmutation]

Under https://learn.hashicorp.com/vault/operations/raft-storage-aws#resume-normal-operations
The Vault_3 is listed as the only member in the cluster.

I stopped and tried to force the join of the cluster by Vault_2 and Vault_4 but they will not joing Vault_3 the one where the recovery procedure is run.

Can you please clarify what needs to be done to return the cluster to its initial state of 3 nodes.

Cluster reset: When a node is brought up in recovery mode, it resets the list of cluster members. This means that when resuming normal operations, each node will need to rejoin the cluster.

I tried this but got the following errors back... from Vault_2 and Vault_4

Error joining the node to the raft cluster: Error making API request.
