This configuration work for me in both development and production.
environments:
development:
grails:
mongodb:
host: "localhost"
port: 27017
username: ""
password: ""
databaseName: "mydb-dev"
production:
grails:
mongodb:
host: "1.1.1.1"
# host: "localhost"
port: 27017
username: ""
password: ""
databaseName: "mydb-prod"
I'm using Grails 3.1.9 and latest MongoDB plugin.
compile 'org.grails.plugins:mongodb'

If you still want to use a connection string instead of supplying all of the parameters separately, you can use url as listed below:
environments:
development:
grails:
mongodb:
url: "mongodb://192.168.1.13:27017/test"
This approach also allows you to supply query parameters where necessary. The documentation can be found in the gorm manual under the MongoDB Connection Strings section.
