Kontact запускается, но не подключается к моему календарю/контактам dav (через экземпляр nextcloud). Так что это выглядит так, как будто это был первый запуск (интересно, что в настройках мои календари/контакты отображаются и говорят мне, что все готово и синхронно)

Любые предложения, как я могу решить эту проблему?
