3. Android 8.1 with iCloud, "No CalDAV/CardDAV service found"

Android 8.1 with iCloud, "No CalDAV/CardDAV service found"

  • ?

    Hello,
    I am getting the error “No CalDAV/CardDAV service found” when trying to add an iCloud account. URL, name, and pw are checked. It worked on Android 6, but on Android 8 not. It seems apple blocks this request with new header/http/device information.

    This line

    2018-11-23 17:26:31 320 [ui.setup.DavResourceFinder] carddav service discovery failed

    is different compared to post in

    Somehow the auto-detection in ui.setup.DavResourceFinder does not work for me, however there’s a workaround:

    One account for calendar, basis-URL: https://p45-caldav.icloud.com
    One account for contacts, basis-URL: https://p04-contacts.icloud.com/[uniqueid]/carddavhome/card/

    uniqueid can be found in calendar log or xhr when going to icloud.com

    Sounds like iCloud has changed their redirects, maybe temporarily? Sometimes this happens and then it works again some time later…
