Misleading error if file has wrong permissions

[MightyPork]

I had some music files that had permissions 660, so Emby couldn't read them by its user.

This error does not help:

I thought it isn't able to stream Flac, so I converted it to mp3 but that still didn't play. Then I checked permissions and found the issue. Would be great if this (probably somewhat common?) problem was better reported

Running Emby 4.8.10.0 in docker on Linux

Hi there, please attach the emby server log from when this happened. Thanks.

This one?

It is super easy to reproduce, just chmod some file so emby can't read it. The same error message shows with video files.
