The l.php which Newsblur uses to redirect from the feed-view to linked websites responds with 404-Errors while trying to follow otherwise perfectly fine links.
One Example:
http://www.newsblur.com/l.php?u=https://itunes.apple.com/jp/app/mojipad-written-planner-for-the-digital-age/id1132431009?mt=8&uo=4&at=1l3vx5v&ct=techjo
If I remove the prefix “http://www.newsblur.com/l.php?u=” the link is valid. With the prefix, i get a “404 · NewsBlur can’t find that page”.
The link is from the feed-view of this Japanese site: https://isuta.jp/category/iphone/2018…
