My Music Library (on a NAS drive) is not accessible (again - it was back for a few days in late October) from my iPhone/iPad Sonos app.

I can see and access it  from my MacOS app (and my playlists), and am able to play albums, playlists from MacOS, but the library just isn’t visible from the iPad or iPhone.

I’ve tried rebooting all the devices, and checked that the apps are up to date.

 I tried deleting and re-entering the share path to the share on both the iPhone and iPad:

//IAN-MEDIA-SERVE/Public/Shared Music   (no uername/passwored needed)

(this is the same path used on the MacOS App).

but I get the error message “Unable to Connect - check the username and password”

There is no username and password for this path ….. .
