Can you share the path that you’re trying to enter into Nucleus for the NAS folder? Are you entering the username and password as well?
I managed to get it up running in terms of having my Nucleus+ watching music files saved on my Synology DS 216j in shared music folder. All working on the same network.
The issue is, I can’t get the DS 216j to
copy files direct to the internal storage on the Nucleus+
make a backup on the same Nucleus+ internal storage to the DS 216j or usb hdd linked to the DS 216j directly.
The Nucleus+ is able to make scheduled backup of Roon database to DS 216j without problems.
How are you trying to do this (via Finder or File Explorer)? Are you getting any errors when trying to copy files?
Can you clarify the above for me? You mention that you can schedule a backup to the DS216j without problems. Does the backup not go through at the selected time? Are you receiving any errors?
Typically using File Explorer or Finder is the best option for transferring files. How are you trying to do this on your NAS directly? Do you receive any errors when trying to do this?
How are you trying to do this from the NAS? Are you receiving any specific errors?
