OpenShift MongoDB ECONNREFUSED

Question

When attempting to connect to the mongodb-2.4 cartridge i keep getting the following

 ==> app-root/logs/nodejs.log <==
  Error: connect ECONNREFUSED 127.0.0.1:27017
      at Object.exports._errnoException (util.js:893:11)
      at exports._exceptionWithHostPort (util.js:916:20)
      at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1075:14)

I am creating the connection string as below

if(process.env.OPENSHIFT_MONGODB_DB_PASSWORD){
  connection_string = process.env.OPENSHIFT_MONGODB_DB_USERNAME + ":" +
  process.env.OPENSHIFT_MONGODB_DB_PASSWORD + "@" +
  process.env.OPENSHIFT_MONGODB_DB_HOST + ':' +
  process.env.OPENSHIFT_MONGODB_DB_PORT + '/' +
  process.env.OPENSHIFT_APP_NAME;
}

It looks like when it fails it thinks the port is 27017 but when i run rhc port-forward appname it shows me the following different port for mongodb

Service Local                OpenShift
------- --------------- ---- ------------------------------------------------------
haproxy 127.0.0.1:8080   =>  127.6.174.2:8080
haproxy 127.0.0.1:8081   =>  127.6.174.3:8080
mongodb 127.0.0.1:42346  =>  5747fa8f70-appname.rhcloud.com:42346
node    127.0.0.1:8082   =>  127.6.174.1:8080

Any ideas as to whats going wrong?

So turns out if you remove a mongodb cartridge after it has been deployed alongside the web servers cartridges and then replace the mongodb cartridge the web server variables don't get updated. I needed to restart the web tier servers in order for them to the get the new mongodb setting variables updated.
