Can't download reviews from stores different from the "United States" store

Hi, similar to another issue posted here I have the problem that I'm not able to scrape from a store different to the "United States" store. Means that

"python applestore_spotify_us.py -i 324684580 -c 'United States' -m 1000"

works fine, while, for example,

"python applestore_spotify_de.py -i 324684580 -c 'Deutschland' -m 1000"

gives me the following error: "Can't connect to the AppStore, please try again later."

I'd really appreciate any help and in advance, many thanks for doing so!
