Hi,

I am trying to setup CalDAV and CardDAV for FastMail with Kontact.

KOrganizer > Calendar > Add
DAV Groupware resource > entered my username and password > Configure resource manually.
Server configuration > Add > Remote URL and tried both global and specific credential.

It prompted me that the server doesn't require encryption which is not what FastMail's docs say. It eventually prompted 404 there was a problem with the request with a dead end.

How can I setup KOrganizer and KAddressbook with FastMail?
