Hey MongoID Team,

I have a replica set with 2 nodes, running on Linux. with the mongo shell I can connect to both nodes. But via the mongoid.yml config file I get this error message:

/opt/local/lib/ruby1.9/gems/1.9.1/gems/mongo-1.5.2/lib/mongo/repl_set_connection.rb:165:in `connect': Failed to connect to primary node. (Mongo::ConnectionFailure)

My mongoid.yml looks like that:

development: 
    host: localhost
    database: myapp_dev
    
test: 
    host: localhost
    database: myapp_test

production: 
    database: myapp_prod
    hosts: 
        - - node1
          - 2111
        - - node2
          - 2111
    read: :primary

I googled already, but I coulnd't find anything useful. Please help me out.
Thx.
