I am getting the following error with MyKolab. Any suggestion for troubleshooting?:

My config:

Org-Caldav

+BEGIN_SRC emacs-lisp

(use-package org-caldav :ensure t :config (setq org-caldav-url "https://apps.kolabnow.com/calendars/username%40mykolab.com/26df37ad-2345-4bfe-1976-ac115abeb8fd" org-caldav-calendar-id "Calendar" org-caldav-inbox (concat org-directory "/gtd.org") org-icalendar-timezone "Africa/Juba" org-caldav-files nil)

[pauljamesharper]

Found the problem. In my case I had to use my full username@mykolab.com as the password.

I also had to put the link to the calendar as per the first example:

;; The CalDAV URL with your full and primary email address at the end. (setq org-caldav-url "https://apps.kolabnow.com/calendars/username%40kolabnow.com")

And NOT as per Step 4 and 5 of the Show Calendar URL in the Emacs Client Configuration.
