I have changes the server.js file to use "module.exports = 'http://nodepli-devicemapping.rhcloud.com/';" instead of "module.exports = localhost" but it still not working.
http://nodepli-devicemapping.rhcloud.com/ is the URL to multi instance application.
Where else do we need to change in the code to make it run like "http://multi.christine-coenen.de/" ..
