Describe the bug

I made account to https://nch.pl/ Nextcloud server and Gnome Online accounts connects successfully to this server. With the same server and login info I can't connect Reminders to CalDAV server. Sign in button does nothing, there is no any errors in GUI.

With terminal I have following output when pressing to Sign in button:

Traceback (most recent call last):

What is wrong in this case?

To Reproduce

1. Open Reminders
2. Open Preferences
3. Open CalDAV -> Add account
4. Fill fields with Nextcloud creditenials
5. Click to the "Sign in" button
6. Nothing changes in GUI side, no errors
7. Account is not included and there is no CalDAV connection to sync

Logs

No response

Additional context

Figured out that right and working WebDAV address is under the Nextcloud calendar settings in my case this is https://nch.pl/remote.php/dav not primary Nextcloud server address https://nch.pl/

With wrong creditenials there must be some visible error.

When I try to mark Nextcloud demo tasks to complete within Reminders "Something went wrong" window pops up:
