Meteor Up - Error: connect ECONNREFUSED 192.168.100.12

I have a Meteor App based on Angular 1.3 + Meteor 1.5.2.2.
I am using Ubuntu 17.
I am trying to deploy my Meteor App on local machine first before going for live server using Meteor Up.
But I am facing this issue when running mup setup command

martinihenry@martinihenry:~/mytestapp-prod/.deploy$ mup setup

Started TaskList: Setup Docker
[192.168.100.12] - Setup Docker
events.js:141
      throw er; // Unhandled 'error' event
      ^

Error: connect ECONNREFUSED 192.168.100.12:22

    at exports._exceptionWithHostPort (util.js:930:20)

Here is my mup.json:

module.exports = {
  servers: {
    one: {
      // TODO: set host address, username, and authentication method
      host: '192.168.100.12',
      username: 'root',
      // pem: './path/to/pem'
      // password: 'server-password'
      // or neither for authenticate from ssh-agent
    }
  },

  app: {
    // TODO: change app name and path
    name: 'mytestapp-prod',
    path: '../',

    servers: {
      one: {},
    },

    buildOptions: {
      serverOnly: true,
    },

    env: {
      // TODO: Change to your app's url
      // If you are using ssl, it needs to start with https://
      ROOT_URL: '192.168.100.12:3000',
      MONGO_URL: 'mongodb://localhost/meteor',
    },

    // ssl: { // (optional)
    //   // Enables let's encrypt (optional)
    //   autogenerate: {
    //     email: 'email.address@domain.com',
    //     // comma separated list of domains
    //     domains: 'website.com,www.website.com'
    //   }
    // },

    docker: {
      // change to 'kadirahq/meteord' if your app is using Meteor 1.3 or older
      image: 'abernix/meteord:base',
    },

    // Show progress bar while uploading bundle to server
    // You might need to disable it on CI servers
    enableUploadProgressBar: true
  },

  mongo: {
    version: '3.4.1',
    servers: {
      one: {}
    }
  }
};

What could be wrong here?

Can you connect to that server via ssh ?

How can I do that? I am new to all this.

If you’re on windows, download Putty, if on Mac/Linux open the terminal and do ssh IP

service ssh restart says: Failed to add /run/systemd/ask-password to directory watch: No space left on device

Have any resolved?
I has the same problem (Mac).
