iCloud problem - 501 Not Implemented.
This morning my android (6) phone with DAVv5 connected to two iCloud account (one for contacts, one for calendar) was working fine. This afternoon, my icloud contacts and calendar had all vanished from my phone, and DAVv5 showed no accounts registered.
Trying to add my iCloud accounts back in just gets “Couldn’t find CalDAV or CardDAV service. Looking at SHOW DETAILS, and it seems that the iCloud severs are returning 301 Redirect from https://icloud.com to https://www.icloud.com/ and then returning 501 Not implemented.
Any ideas? Perhaps it’s a temporary blip?
It was a temporary blip. Now all working again. Very strange.
