Interesting that both of these feeds show the same issue, which is that NewsBlur feed fetchers are being forbidden (403 error) by IP address. Can you reach out to these two sites and let them know they are banning NewsBlur’s feed fetchers? Let the publishers know that the IP addresses they should expect to see are listed at https://www.newsblur.com/api/ip_addresses/.
I also reached out to both publishers to ask that they allow NewsBlur to fetch their feeds.
Here’s what I sent:
Hi, I run NewsBlur, an RSS news reader, and my users have complained that this site’s RSS feed is preventing NewsBlur’s feed fetchers from fetching it. NewsBlur publishes the IP addresses of its feeds at: https://www.newsblur.com/api/ip_addresses/. May I ask that you open up your RSS feed to NewsBlur? And it would be super helpful if you could let me know why it was banned in the first place, as there are a number of other feeds that have this same issue. Are you using Cloudflare or some other CMS that bans bots? Thanks for your help!
