  },
  subdivisions: [ { geoname_id: 1111111111, iso_code: 'SP', names: [Object] } ]
}

But one ovpn client return a object without some values:

loc : {
   registered_country: {
     geoname_id: 1111111,
     iso_code: 'BR',
     names: {
       de: 'Brasilien',
       en: 'Brazil',
       es: 'Brasil',
       fr: 'Brésil',
       ja: 'ブラジル連邦共和国',
       'pt-BR': 'Brasil',
       ru: 'Бразилия',
       'zh-CN': '巴西'
     }
   }
 }

Then we have a problem at this line: https://github.com/AuspeXeu/openvpn-status/blob/bcc0129004d296292db4b75d91cbd4e175073dbf/server.js#L74

To resolve for moment I write the iso_code, name, lat and lon with registered_country value or default, but it isn't apropriate for resolve the error...

I see that object its related with maxmid database, so the error can be related with this package or data
