Nextcloud public shares with password – Auth failure

WinSCP versions: 6.5.6 and 6.6.1 beta - GUI
MS Windows 10 Pro 22H2 and 11 Pro 25H2
WebDAV – NextCloud versions 32.0.8 and 33.0.2

Hi,
I have problems connecting to Nextcloud public shares, only if a password is requested.
With private shares (Nextcloud path /remote.php/dav/files/USERNAME) there are no problems, the auth process is ok and the credentials are accepted.
With public shares (Nextcloud path /public.php/dav/files/USERNAME) there are no problems if no password is set on the share, but if a password is required this error occurs:

401 Unauthorized - Connection failed.

With rclone and Cyberduck there are no problems at all, so I think it's a bug of WinSCP.

Thanks for your report. I'll look into it.

I wanted to test the Nextcloud. But it seems that they do offer only 1-hour tried. What seems like too short for any serious debugging. Would it be possible for you to setup a test share for me?
