Playlist's are not working

Hi, last week I replace my wifi router.
Everthing work fine, my NAS still have the same ip (static ip) from the old router.
Made a fresh Volumio install, set my Myvolumio acount and get back my playlists.
But I can’t playback my playlist’s, Volumio want to load it but when press play nothing happend.

I can make new playlist’s, but when I delete those playlists after a reboot there are back…
How can I fix this?

Still busy with this problem.
When i’m putt songs in queue and save it over the old one and do a reboot the unplayable songs are back again…
