Vault
,

I deployed HA vault cluster in local kubernetes (docker desktop). This is without TLS. I have a copied the overide values below,

# Vault Helm Chart Value Overrides
global:
  enabled: true
  tlsDisable: true     

server:
  dataStorage:
    enabled: true   
    size: 5Gi    
    mountPath: "/vault/data"  
    storageClass: null    
    accessMode: ReadWriteOnce    
    annotations: {}
  auditStorage:
    enabled: false
  standalone:
    enabled: false
  image:
    repository: "hashicorp/vault"
    tag: "1.6.3"

  resources:
    requests:
      memory: 256Mi
      cpu: 200m
    limits:
      memory: 512Mi
      cpu: 400m
  affinity: ""  
  readinessProbe:
    enabled: true
    path: "/v1/sys/health?standbyok=true&sealedcode=204&uninitcode=204"  
  ha:
    enabled: true
    replicas: 3
    raft:
      enabled: true
      setNodeId: true
      config: |

        ui = true

        listener "tcp" {

          tls_disable = 1

          address = "[::]:8200"

          cluster_address = "[::]:8201"

        }

        storage "raft" {

          path = "/vault/data"

        }

        service_registration "kubernetes" {}

    config: |

      ui = true

      listener "tcp" {

        tls_disable = 1

        address = "[::]:8200"

        cluster_address = "[::]:8201"

      }

      service_registration "kubernetes" {}

# Vault UI
ui:
  enabled: true
  serviceType: "ClusterIP"
  externalPort: 8200

When I try to add the other pods to the raft cluster I am getting the following error,

I followed the following doc. I am not sure what I am doing wrong here. Any suggestions
