> You can not setup Calendar/Contacts together. You need to setup them **separately**.

6.  Select **Manual** as Account Type and type in your respective credentials:

    **Username**: Your Nextcloud username or email

    **Password**: Either your password or if you use 2FA your generated app-password/token ([Learn more](/link/881)).

    **Server Address**: URL of your Nextcloud server (e.g. `https://nextcloud.yourdomain.com`)

7.  Click on **Sign In**.

## Troubleshooting

- macOS does **not** support syncing CalDAV/CardDAV over non-encrypted `http://` connections. Make sure you have `https://` enabled and configured on server- and client-side.
- **Self-signed certificates** need to be properly set up in the macOS keychain.
