This is in reference to a GitHub question posted here: https://github.com/hashicorp/consul/issues/7927
I setup vault with consul cluster in AWS using Terraform. they set up ran for a month and all the sudden it starts giving me an error.
500 (The backend responded with an error)
2 vault servers
2 consul servers.
initial diagnosis suggests that no leader is selected.
##consul operator raft list-peers -stale
Error getting peers: Failed to retrieve raft configuration: Unexpected response code: 500 (No cluster leader)
