Playlist import always shows up as empty

[theibot]

When scanning an qr-code the app always states that it is "empty", which it simply is not. I seems like the fix from Kisa04 doesn't work anymore (when I put in my playlist URL into the noembed URL on my PC it says 400 Bad request), is there any known workaround, or am I just missing something else?
I would greatly appreciate some help.
