I try to deploy my Mongo database in Mongolabs, everything works fine, and I create a new database. Please see my connectionstring.
public DbHelper()
{
MongoClientSettings settings = new MongoClientSettings()
{
Credentials = new MongoCredential[] { MongoCredential.CreateCredential("dbname", "username", "password") },
Server = new MongoServerAddress("ds011111.mongolab.com", 11111),
//ConnectTimeout = new TimeSpan(30000)
};
Server = new MongoClient(settings).GetServer();
DataBase = Server.GetDatabase(DatabaseName);
}
but when I try to connect the database it's shows error like:

Add "?connect=replicaSet" to the end of your connection string if connecting to MongoLab.
new MongoClient("mongodb://username:password@ds011111.mongolab.com:11111/db-name?connect=replicaSet")
This JIRA ticket has some details: https://jira.mongodb.org/browse/CSHARP-1160
Basically the default is to connect to a replica set member. But MongoLab's Single-Node settings are actually a single node replica set and this causes us to not trust it. Appending ?connect=replicaSet to your connection string will force the driver to move into replica set mode and all will work.

I am replacing the connection string method in like below.
new MongoClient("mongodb://username:password@ds011111.mongolab.com:11111/db-name")
Now it's solved.
Please see the answer from Paul Lemke.

Make sure your current ip address is white-listed in mongo db server. If you change your internet provider new IP needs to be white-listed.
