I'm currently confused by what my Sonos system (or rather, its software) is trying to tell me. I just updated my server's OS a few days ago, when suddenly Sonos wasn't able to access the Samba/NAS share on that device any more, stating access was denied. I removed my music library folder using the Sonos App (on my Windows PC) and tried to re-add it, again resulting in an "Access denied" error. The same occurs when I try to re-add my NAS folder via Android App.
The directory permissions in the (path to the) Samba share folder were not altered, and also the smb.conf file was not modified in any way. Accessing the Samba-enabled folders on my server still works fine from my Windows PC as well.
Does anyone have an idea what else may be the reason for the sudden loss of access to my Samba share folder?
