Does the https://caldav.icloud.com still work for you guys?
My credentials are right, the rest of the conig is same as the config,
I get this error:

pi@raspberrypi:~ $ vdirsyncer discover
Discovering collections for pair iCloud_to_MagicMirror
Mirror:

Get an error if I type vdirsyncer discover -vdebug (no such option)
