Not working withy me. I am getting the message:

You can try entering the MONGO_URL value through the Heroku control panel too. Search for Config Variables in the settings and enter the URL that mLab gives you. Watch out for typos and if you’re testing it locally make sure that your ISP does not block certain ports that might have failed the authentication check (e.g. My campus wifi connection blocks mLab and any SSH attempts)
