CalDav integration not working with iCal

[keen valley]

I've read quite a few Reddit posts on this and read through the CalDav integration support article and have not been able to figure out why my iCal calendar is not able to be pulled in via the CalDav integration or the direct config.yaml route.

For the url, I have copied the url from the calendar I want to share on iCloud and replaced the beginning with "https://" instead of "webcal://" (see attached screenshot)

For the username I am using my full iCloud account email.

For the password I generated an app-specific password.

The error I get from the native CalDav integration is very brief and ambigious: "Failed to connect"

Anything I'm doing wrong here? Thanks!

I have the same problem and have tested using http, https, webcal, with and without validate SSL… Does this integration no longer work?

I second this issue, my CalDAV integration that hooks into the *DAV-interface of Nextcloud stopped working all out of the sudden. No idea how or why, all other DAV-enabled clients still work perfectly fine.

Error as seen in the Docker logs of HA:
