ICloud 403 error when syncing non-all-day task

DAVx⁵

    Hi,

    I am getting a 403 unauthorised error when trying to sync tasks with iCloud using Davdroid.

    This only happens when setting a specific time for events, when editing or creating new tasks on my Android device.

    However, the tasks are synced fine when changing all other attributes, and sync fine when enabling “All Day” option.

    Thanks.

    This is the log I am getting:

    The issue can be replicated by doing the following:
    1.) Create a new task using a particular date and time, and timezone.
    2.) Go to settings > account > force sync (of DavDroid account containing tasks)
    3.) Error pops up and sync fails.

    Error does not occur when a date is not set. For example, creating a new task with all day enabled, or no dates specify means that no error occurs.
    This error also happens when editing or completing already existing tasks from iCloud which have a time.

    Client software:
    Davdroid 0.8.0 and Tasks (Marten Gajda)
    Server: Apple servers (iCloud)

    Thanks for the extensive information. Unfortunately, the setprop calls from https://github.com/bitfireAT/davdroid/wiki/How-to-view-the-logs where not done, so traffic was not logged.

    Which time zone? Does it work with other time zones?

    Is Apple’s two-factor authentication disabled?

    Yes 2 factor authentication is disabled.

    As I said, syncing works fine unless a task contains a populated time field.

    No, has still to be investigated. I guess that the created iCal file is somehow not acceptable for iCloud. If you have time and experience, you could try to do the PUT request manually with different content and find out which field causes the error.

    The error is caused by the time field. If a task is created without a time
    field, then the error does not occur. If a task is created with a time
    field, then the error occurs.

    Therefore, setting a task as ‘All Day’ means that synchronisation is fine.
    If instead of ‘All Day’, specific time is specified, then the error occurs.

    Completing, or editing a task which contains a time field will result in
    the error as well.

    Can’t reproduce the problem here, adding/modifying task on iCloud via DAVdroid works (with time fields set).

    06-17 14:25:08.001  27754-12389/at.bitfire.davdroid:sync D/Wire﹕ http-outgoing-9 >> "DUE;TZID=Europe/Malta:20111111T090000[\r][\n]"

    I wonder how you could set the Malta time zone? My Android devices don’t show this time zone.

    Can you please try to add a new task with another time zone, for instance Europe/Vienna and see whether it works?

    Seems to be working now. I don’t kniw what happened. Could have been some kind of misconfiguration on Apple’s side. Will reopen if problem resurfaces.
