"Invalid ns" when connecting to mongodb server

Question

Im trying to connect to a MongoLabs mongodb server I setup for a small project Im working on. I can connect fine when connecting from my local machine, but when I try to make a connection from my Mediatemple server I get a 'Invalid ns' error:

Unable to connect to MongoDB: Failed to connect to: dsXXXXXX.mongolab.com:27769: send_package: the query returned a failure: Invalid ns [XXXXXX_dev/XXXXXX_dev.$cmd] (code: 16256)

Any suggestions on how to fix this would be a major help.

Solution

Perhaps your database name in your connection string or collection name (together they make a namespace) have special characters, and they make the namespace name illegal.

So you should make sure your connection string is ok.

For example, mine looks like

mongodb://mydblogin:[email protected]:44444/mydatabase

Also make sure that collection name is legal.

In my case, the database name was empty.
