Run kamal setup: Exception while executing on host 192.168.0.1: Net::SSH::ConnectionTimeout

Hi guys, I'm newbie in kamal.

It's really a great tool for deployment. Thanks to @dhh . But I have some difficulties deploying despite having read the documentation.

After configuring the deploy.yml file like this:

# Name of your application. Used to uniquely configure containers.
service: soe

# Name of the container image.
image: noumedem/soe

# Deploy to these servers.
servers:
  web:
    hosts:
      - 51.68.124.156
    labels:
      traefik.http.routers.soe.entrypoints: websecure
      traefik.http.routers.soe.rule: Host(`www.jeteste.site`)
      traefik.http.routers.soe.tls.certresolver: letsencrypt
    options:
      network: 'private'

# Credentials for your image host.
registry:
  # Specify the registry server, if you're not using Docker Hub
  # server: registry.digitalocean.com / ghcr.io / ...
  username: noumedem

  # Always use an access token rather than real password when possible.
  password:
    - KAMAL_REGISTRY_PASSWORD

# Inject ENV variables into containers (secrets come from .env).
# Remember to run `kamal env push` after making changes!

    - POSTGRES_PASSWORD

# Use a different ssh user than root

# hitting 404 on in-flight requests. Combines all files from new and old
# version inside the asset_path.

# Configure rolling deploys by setting a wait time between batches of restarts.
# boot:
#   limit: 10 # Can also specify as a percentage of total hosts, such as "25%"
#   wait: 2

# Configure the role used to determine the primary_host. This host takes
# deploy locks, runs health checks during the deploy, and follow logs, etc.
#
# Caution: there's no support for role renaming yet, so be careful to cleanup
#          the previous role on the deployed hosts.
# primary_role: web

# Controls if we abort when see a role with no hosts. Disabling this may be
# useful for more complex deploy configurations.

# allow_empty_roles: false

When I runkamal setup , I get this errors: ERROR (Net::SSH::ConnectionTimeout): Exception while executing on host 192.168.0.1: Net::SSH::ConnectionTimeout

kamal setup -> ouput:

  ERROR (Net::SSH::ConnectionTimeout): Exception while executing on host 192.168.0.1: Net::SSH::ConnectionTimeout

Before running kamal setup in local, I did these steps in my VPS:

sudo apt update
sudo apt upgrade -y
sudo apt install -y docker.io curl git
sudo usermod -a -G docker ubuntu
sudo docker network create --driver bridge private
sudo mkdir -p /letsencrypt && sudo touch /letsencrypt/acme.json && sudo chmod 600 /letsencrypt/acme.json

How can I solve this problem? Please help.
