figured out that the subf2m provider somehow uses the localized title of the movie for building the query.
an example which yields no result (using the danish title) is;
https://subf2m.co/subtitles/searchbytitle?query=goonierne
the logs say:
https://subf2m.co:443 "GET /subtitles/searchbytitle?query=goonierne&l= HTTP/11" 200 None
manually using the original title in a chrome browser and I get a result.
eg.
https://subf2m.co/subtitles/searchbytitle?query=goonies
I can even use the IMDB id like:
https://subf2m.co/subtitles/searchbytitle?query=tt0089218
This way I also get a result.
