Can't ssh into a VM with any key

[screwyy]

Hello,

Packer version: 1.9.1
plugin version: 0.4.0

I'm not using the latest version of the plugin because I want to specify the network ID in order to test ssh to the VM.
By default packer creates the VM in 172.16.0.0/16 network and it's not good because I also have a network like that from where I run packer and it complicates the testing of SSH to it with peering/routes/security groups etc.

I am trying to create a new Image with packer based on Rocky 9.0 but packer can't ssh into it, while I am able to use the same key and before it destroys the VM I can connect to it
This is my code:

cat ~/workspaces/golden_image/image.json.pkr.hcl
source "huaweicloud-ecs" "ecs" {
  access_key       = "***"
  auth_url         = "https://iam.eu-west-0.prod-cloud-ocb.orange-business.com"
  flavor           = "s6.medium.2"
  image_name       = "Rocky-90_golden_0.0.1"
  networks         = ["031ef2ca-cc74-48a1-99cc-38b124441f91"]
  project_name     = "eu-west-0"
  region           = "eu-west-0"
  secret_key       = "***"
  security_groups  = ["ebc8291d-5368-4552-a65a-5bdd0b22f057"]  # this is the default SG
  source_image     = "7f85e7c0-b63a-4868-a273-0d6209c13d67"
  ssh_ip_version   = "4"
  ssh_username     = "cloud"
}

build {
  sources = ["source.huaweicloud-ecs.ecs"]

  provisioner "shell" {
    inline = ["sudo yum update -y; sudo sed -i -e 's/.*rocky-90-golden-1/%LOCALIPV4%  %LOCALHOSTNAME%.malima.internal %LOCALHOSTNAME%/' /etc/hosts"]
  }
}

This is the output:

If I remove the networks and upgrade the plugin I have the same issue (but can't test anymore)
