Unable to connect to Nextcloud Music Subsonic Server

[driacats]

Hello everyone, Looking for a subsonic player for my new Nextcloud server I found Jellycli. I tried to connect to the subsonic server given from the music app in Nextcloud, I generated a password for the application and I tried to insert those information when requested from Jellycli after have changed the server in the config from Jellyfin to Subsonic as written in the documentation. What I got is this error:

Am I missing something? Is there any solution? I also tried Sublime Music and it works so I guess on my side on Nextcloud the server is well configured.

Does Nextcloud's log include anything related? Or LDAP server's log since you seem to be using LDAP.
