[PROBLEM] New user, trouble to create library to connect to a synology nas

[the_bertrum]

I'm sharing from DSM 7.1.1 over Samba. No need for SMB1.0 to be enabled (I've got 2.0 as the minimum that the NAS will allow). I have a user for all my Raspberries to use which is given Read/Write access to the music share on the NAS. The scan never finds the share, but it maps perfectly well with <servername>.local/music manually entered.

I'd check that the user you set up has read/write on the share on the NAS as a first step.
