Update to NC 11 seems to break integration with Gnome

[despens]

Steps to reproduce

1. Open Gnome Online Accounts
2. Add new "owncloud" account (nextcloud not available) by adding URL of the server
3. Tick all boxes to integrate calendars, contacts, documents and files

Expected behaviour

Gnome desktop apps should use nextcloud as a data source

Actual behaviour

Since NC11, integration with gnome contacts and calendars is not working anymore.

@despens @der-daniel with the next version of GNOME, it will be switched to Nextcloud. :)
Thanks to @debarshiray & @jimmac of GNOME for making it happen! ❤️

But even then, Nextcloud should work fine too, since it’s all WebDAV. Any idea @debarshiray?

[flortsch]

It's working for me with Gnome 3.22 at least.
Also related to #3006 I guess.

[debarshiray]

There shouldn't be any change between GNOME 3.18 and 3.22 regarding this. The GNOME components expect the following endpoints:
(a) WebDAV: /remote.php/webdav/
(b) CalDAV: /remote.php/caldav/
(c) CardDAV: /remote.php/carddav/

Are those endpoints working? You can point a web browser at them to do a basic smoke test.

Can you browse your Nextcloud files using Nautilus?

[despens]

The problem has disappeared with upgrade to 11.0.2 (stable)

[jancborchardt]

Thanks for testing! Closing hence. :)
