The error message is not very good, but it indicates that the DAV server has returned an invalid response.

Is this some standard DAV server (like Nextcloud), or some custom/proprietary one? Are you able to test with some other calendar client?

It's Nextcloud, and it works with Evolution and GNOME Online Accounts, as well as with DAVx5 on Android.

Notably, it wasn't an issue when connecting to OpenDesktop.org Cloud (an older version of Nextcloud), so I think it might be related to a change in Nextcloud.

Potentially the same as https://bugs.kde.org/show_bug.cgi?id=486871, the error message is indeed not helpful, but I got the same.
And I can confirm that the ressource is working with every other client, including akonadi < 6.*, so this is not a bug in the ressource, but in akonadi.
