Trouble when creating Replica Set

[Nykeriab]

I want to convert a Standalone to a Replica Set for my MongoDb instance. I'm using Terraform and Helm and I manage K8s with my provider (Scaleway). The Helm file I'm using is : https://artifacthub.io/packages/helm/bitnami/mongodb

I can create 2 replicas and one arbiter, but they shut down until a short moment, in my terminal they seems to be in a loop. I've got some error messages which are :

readiness probe fail.

I'm new at Devops.

Here is my Terraform config :

resource "helm_release" "mongodb" {
  depends_on = [kubernetes_secret.tls_mongo]
  name       = "mongodb"
  repository = "https://charts.bitnami.com/bitnami"
  chart      = "mongodb"
  version    = "11.1.0" 
  namespace = "mongo"
  set {
    name  = "image.tag"
    value = "4.2"
  }
  set {
    name  = "auth.rootUser"
    value = var.mongo_username
  }
  set {
    name  = "auth.rootPassword"
    value = var.mongo_password
  }
  set {
    name  = "persistence.size"
    value = "10Gi"
  }
  set {
    name = "architecture"
    value = "replicaset" # standalone or replicaset
  }
  set {
    name = "auth.replicaSetKey"
    value = var.MONGODB_REPLICA_SET_KEY
  }
}

Here are the status of my pods : The first pict is when they 're running and everything is fine. The other pict of the pods status is when everything is driving me crazy.

Can someone help me?

Logs of the events after this command

kubectl describe pod mongodb-arbiter-0

Can you share output of

kubectl describe pod mongodb-arbiter-0

Mainly interessting are events at the end if possible within timeframe when you start the deployment until it crashes.
