Operating system and version :
The issue you are facing: I can’t add my Nextcloud calendar/contacts as a CardDav/CalDav account on iPadOS using a Nextcloud instance with Oauth2 authentication.
This is because I do not get an authentication redirect to my Oauth2 provider.
Is this the first time you’ve seen this error?: Yes. I did not try this with an iPad before.
Steps to replicate it:
- Use a Nextcloud instance with Oauth2 as authentication
- Try to log in with your Oauth2 provider credentials
- It fails as expected, as Nextcloud cannot authenticate you
The output of your Nextcloud log in Admin > Logging:
Login failed: '[user name redacted]' (Remote IP: '[redacted]')
On Android, the Nextcloud app has a „Add contact/calendar“ function (in the settings) that sets up Davx5 appropriately. This works with an instance using Oauth2.
On iPadOS, the Nextcloud app does not have a similar option. Is it possible to do this in a different way?
