De Stentor:nieuws rss feeds doesn’t work

These De Stentor:nieuws rss feeds don’t work in newsblur, in other competing rss apps they just work. They seem like very ordinary rss addresses to me. I don’t see anything special about it. Why don’t you think these are working? The solution that newsblur itself gives doesn’t work either. Wouldn’t know how to fix this. Thank you in advance.
