Help with Ubooquity new-setup - can't see my books

Greetings All, I'm new user to Ubooquity, finding it very fascinating and matching my simple needs to read my books collection over browser if possible. to keep it simple, instead of raspberry pi, I'm using old i386 headless linux box with some SSD attached for plex and Ubooquity. Everything looks okay though when I try to login with any users I setup to read the books, it throws me back out to user-login screen. so can't see any books.

video capturing the behavior

Below are the logs and setup details.

EDIT

strange though I observed for some reason the scan doesn't reflect the books under 'added/updated' section but only under total.
