All music files exist but the server says all are missing

Latest versions.

I get Playback Error - Please check that the file exists and necessary drive is mounted.

I look at the track and Get Info, Media info, and it says that the file is Unavailable. However, the path and file do exist.

And now all of the music files give this message!

And it worked fine a few hours ago.

I paused when I got a phone call, and when I went back to play, nothing.

I’ve scanned, refreshed, and nothing. Any hints?

It was a permission problem. A weird user didn’t have Read to the files. Changed and works again.

From another post, I was able to find the server logs which pointed me here.
