webDAV mount contains only `lost+found` folder

I want to mount a webDAV remote on my ubuntu 22.04 system. Precisely, this is on a private storage service and is accessible through either

i) my credetials at the link https://pandora.infn.it/ws-my-files/test-webDAV-mount

ii) a public link without passwords: https://pandora.infn.it/public/13359c

I tried following this guide , taking some hints from other sources. The exact steps I did are the following:

1. Install webdav sudo apt-get install davfs2, ensuring to enable non-root mounts.
2. Edit /etc/fstab (I tested both the above links):

$ sudo nano /etc/fstab# append lines:https://pandora.infn.it/public/13359c /home/luca/pandora_public davfs ro,user,noauto 0 0https://pandora.infn.it/ws-my-files/test-webDAV-mount /home/luca/pandora_credentials davfs ro,user,noauto 0 0

3. Add my user to davfs2 group as suggested here:

sudo usermod -aG davfs2 lucasu -l luca

If I check, my user correctly shows davfs2 among its groups:

$ groupsluca adm cdrom sudo dip plugdev lpadmin lxd sambashare davfs2 docker

At this point, I should be able to run $ mount pandora_public or $ mount pandora_credentials, but in either case I am prompted for credentials and get /sbin/mount.davfs: mounting failed; the server does not support WebDAV.

So I also edited /etc/davfs2/davfs2.conf appending ignore_dav_header 1 as suggested here.

Finally, if I re-try it seems both commands ($ mount pandora_public or $ mount pandora_credentials) work and indeed I have a mounted directory. However, mount points only contain a lost+found empty folder.

I suspect it must be something with the authentication since I get the same results even if I use deliberately wrong username and password, however I don't get any error message nor warning. Any help would be much appreciated :D

Hope to have included all relevant details, don't hesitate to ask for more info if needed!
