Keystone and openshift, getting 503 error - mongodb

Question

Can anyone please help me install keystone.js on my openshift app?
I've pushed all my files to the remote, but get a 503 error when I browse to my page. I'm quite new to Openshift, can anyone please point me in the right direction?
I have tried changing keystone.init to:
var connectionString = process.env.OPENSHIFT_MONGODB_DB_USERNAME + ":" + process.env.OPENSHIFT_MONGODB_DB_PASSWORD + "#" + process.env.OPENSHIFT_MONGODB_DB_HOST + dbName;
console.log(connectionString);
keystone.set('mongo', connectionString);
keystone.init({
'mongo': connectionString,
Still no joy, I dont get any console errors either.
Any advice much appreciated.
UPDATE: checked logs and found the following:

Fixed this by making sure all node modules were on the server, pushing to the repo using sourcetree kept timing out, so the modules weren't there. I FTP'd them instead.
