404 error with iCloud

[lyahdav]

I've been trying to connect to iCloud Reminders via CalDAV using this gem. I've been following the test code in https://github.com/loosecannon93/ruby-caldav/blob/master/caldavtest.rb. I'm not sure what the values should be for connecting to the iCloud server but I followed the readme here: https://github.com/n8vision/caldav-icloud. I end up with an error #<Net::HTTPNotFound 404 Not Found readbody=true>. Has anyone successfully used this to connect to iCloud?
