Instead of Der Zauberberg [1984] (DE)/s01e01.mkv, try Der Zauberberg (1984)/der.zauberberg.s01e01.mkv

It is not a problem with parsing file names.
I use nfo files, where I put an explicit URL, like:
https://www.themoviedb.org/tv/84244-der-zauberberg

It is rather an issue with various languages.
TV Show description and and the poster were available only for German language (I eventually added English description to the TV Show)
My language setting was Polish and as far as I understand - Scrapers use English as a fallback, but in this case neither Polish nor English versions of the TV Show were available.

Anyway - I observed that many TV Shows, which could be properly scraped in the last weeks, are scraped now without the poster
The same TV Shows seem to be properly scraped with the Python scraper.

Can confirm that for example, the anime "Shadows House" was properly scraped a few days/weeks ago (not sure), but that's what happens right now: log
