Meteor up - two apps running one virtual server

I’m trying to run two meteor apps on one VPS machine using the Reverse Proxy setup with meteor-up. According to MUP everything is working fine, however, I can only load one of the websites. Both websites run independently on separate VPS machines and there are no errors when I deploy the app to the same server using MUP.

I’ve set both DNS to the same server 11.11.11.111, is this the problem. Port 80 and 443 are open.

Here are my what my mup files look like.

App1: mup.js

module.exports = {
  servers: {
    one: {
      host: '11.11.11.111',
      username: 'myuser',
      pem: 'key'
    }
  },

  app: {
    name: 'App1',
    path: '../',

    docker: {
      image: 'abernix/meteord:node-8.4.0-base',
    },

    // list of servers to deploy to, from the 'servers' list
    servers: {
      one: {},
    },

    // All options are optional.
    buildOptions: {
      // Set to true to skip building mobile apps
      // but still build the web.cordova architecture. (recommended)
      serverOnly: true,
      debug: false,
    },
    env: {
      // If you are using SSL, this needs to start with https
      ROOT_URL: 'https://app1.com',
      MONGO_URL: 'myMonogoDBlink'
    },

    enableUploadProgressBar: true, // default false.
  },

  proxy: {
    domains: 'app1.com, www.app1.com',
    ssl: {
      // Enable let's encrypt to create free certificates
      letsEncryptEmail: 'me@app1.com',
      forceSSL: true
    }
  }
};

App2: mup.js

module.exports = {
  servers: {
    one: {
      host: '11.11.11.111',
      username: 'myuser',
      pem: 'key'
    }
  },

  app: {
    // TODO: change app name and path
    name: 'App2',
    path: '../',

    servers: {
      one: {},
    },

    buildOptions: {
      serverOnly: true,
      debug: false,
    },

    env: {
      ROOT_URL: 'https://www.app2.com',
      MONGO_URL: 'myMonogoDBlink',
    },

    docker: {
      image: 'abernix/meteord:node-8.4.0-base',
    },

    enableUploadProgressBar: true
  },
  proxy: {
    domains: 'app2.com,www.app2.com',

    ssl: {
      // Enable Let's Encrypt
      letsEncryptEmail: 'me@app1.com',
      forceSSL: true
    }
  }
};
