Cloudflare Blog: images are broken

I subscribe to the Cloudflare Blog using https://blog.cloudflare.com/rss/
The feed works fine but it never seems to load the images they show with broken icons, looking at the console I think (I’m not too good at that sorta debugging) like it could be getting a 403 forbidden.
Is there a problem fetching the images using the imageproxy?
Its not a big issue for me, I pop out and load the article if it’s something I wanna see more about but thought I’d report it

Because it’s Cloudflare, they serve HTML when you request images…

So it won’t work because Cloudflare is asking if NewsBlur servers are robots. They were supposed to whitelist NewsBlur, and I believe they did for the RSS feed. But they should also do it for images.
