Unable to access fastweb wowspace webdav (bearer_token fails)

Hello

I've just deleted the previous remote and created a new one using command line only.
Here is the config after replacing the actual user name and password

# rclone config show wowspace2:
--------------------
[wowspace2]
type = webdav
url = https://cloud.wowspace.it/remote.php/webdav/
vendor = nextcloud
user = username
pass = password
--------------------

but I still get the same

rclone -vv tree wowspace2:
<7>DEBUG : rclone: Version "v1.57.0" starting with parameters ["rclone" "-vv" "tree" "wowspace2:"]
<7>DEBUG : rclone: systemd logging support activated
<7>DEBUG : Creating backend with remote "wowspace2:"
<7>DEBUG : Using config file from "/home/user/.config/rclone/rclone.conf"
<7>DEBUG : found headers: 
<3>ERROR : : error listing: couldn't list files: Username or password was incorrect, No 'Authorization: Bearer' header found. Either the client didn't send one, or the server is mis-configured: Sabre\DAV\Exception\NotAuthenticated: 401 Unauthorized
<7>DEBUG : 4 go routines active
Failed to tree: couldn't list files: Username or password was incorrect, No 'Authorization: Bearer' header found. Either the client didn't send one, or the server is mis-configured: Sabre\DAV\Exception\NotAuthenticated: 401 Unauthorized

username and password are correct and I'm able to use them in the web login via browser

I was hopeful about the solution you reported in that post, but I've no idea what to use as a bearer_token

kind regards
