Description Godfrey Hendrix 2021-01-24 19:23:35 UTC 
SUMMARY
My todo list service (Todoist) supports one way calendar feeds which I imported to my Nextcloud calendar. These calendars do not show up in KOrganizer. All my manually created calendars do show up and two way sync is possible and fast. I also setup my iPhone using the same CalDAV link I used with Nextcloud, and I am able to see all the subscribed feeds normally on it.

STEPS TO REPRODUCE
1. Configure KOrganize to sync with a Nextcloud CalDAV user
2. Add a calendar in Nextcloud via the "New Subscription from Link" option
3. Refresh KOrganizer's connection with Nextcloud

OBSERVED RESULT
No calendars subscribed on the Nextcloud instance will be detected/displayed by KOrganizer.


EXPECTED RESULT
Subscribed calendars are detected normally as all other calendars are.


SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma: Arch Linux (Vanilla/Mainline)
(available in About System)
KDE Plasma Version: 5.20.5
KDE Frameworks Version: 
Qt Version: 5.15.2

ADDITIONAL INFORMATION
Issue does not appear to be present on the iOS calendar app.

Could you share what is the user-agent for the request KOrganizer makes when you are requesting for calendars? You can check this from your server logs. This issue of yours could be solved from Nextcloud's end.

Below are the logs generated when I restart the Nextcloud account on KOrganizer. I think it is on that end as my phone (iOS) works fine with the same settings. The native Nextcloud calendar shows up, but the Todoist calendars I subscribe to don't.

Okay, it is this issue with Nextcloud https://github.com/nextcloud/server/issues/17754
kOrganizer (akonadi) could be updated to support webcals on caldav, but for now best way to solve this is to just update Nextcloud with above useragent. I'm going to make pull request of this because I'm having a same issue, and just wanted to confirm the user agent that is being used.

If you want a temporary fix, you can add "/KIO/"  -regex to ENABLE_FOR_CLIENTS array in apps/dav/lib/CalDAV/WebcalCaching/Plugin.php. Do note that this doesn't persist Nextcloud updates. 
Here's an example
