Has the way to connect to the MongoLab database changed?

Question

I have a Bluemix application that is associated with an instance of MongoDB. The application worked for about a year. About a week ago, my application crashed and I was unable to redeploy it. I see the following in the log:

 Instance (index 0) failed to start accepting connections

My code is available in my project https://hub.jazz.net/project/lhayward/Fabulous%20Price%20Finder/overview . Has the connection method to the MongoLab instance changed? Why am I getting authentication errors?
