PLEX not reading files, whats the group and permissions for it?

hey guys, great project.
i’m having problems with my PLEX, it doesnt want to read the files on the Videos folder at all!
i think its a permissions problems, wondering what user:group the dietpi-software assigned to the PLEX installation, tried looking for it but couldnt find it.

edit: permissions problems ON the files in the /mnt/dietpi_userdata/Videos/ files
root:root isnt working either, plex was “thinking” for about 1hour and it came up with nothing.

ls -lah
dietpi@core:/mnt/dietpi_userdata/Video$ ls -lah
