Icloud Caldav stopped working

Configuration
1

Hi,

I have had a calendar in my Home Assistant configuration for a couple of months. It has been working fine until last week. It has suddenly stopped working and I can’t understand why it just stopped or what to do.

My log says that I get “Unauthorized”, which is strange because it has been working all time until last week.

caldav.lib.error.AuthorizationError: AuthorizationError at 'https://p49-caldav.icloud.com/USER_ID/principal/', reason 'Unauthorized'

USER_ID is changed above.

My configuration looks like this:

calendar:
  - platform: caldav
    url: !secret icloud_url 
    username: !secret icloud_username
    password: !secret icloud_app_specific_password
    custom_calendars:
      - name: 'Sara Nattjobb'
        calendar: 'Familj'
        search: 'Sara jobb Natt'

The password is an app-generated-password. I have also tried changing to a new one.

Any ideas of what causes this?

Best Regards
Patrik

I’m having the same issue all icloud calendars show Response error: 400. One event that is set as an all day event is showing properly?

My stupidity. Error due to phone calendar settings. Changed setting on phone and rebooted HA and all is good.
