Playback error - check that the file exists and the necessary drive is mounted

[mlibrik]

Server Version#: 1.23.2.4656
Player Version#: not sure, Plex desktop app for Windows

So this Windows server was running fine, but suddenly I’m getting this playback error message. All the content is visible in the library, but it just won’t play.

What should I do?
