403 error with feed that seems to load fine outside NewsBlur

I recently tried to add Vultr’s feed (https://www.vultr.com/rss/), but NewsBlur reports a 403 error even though it loads fine in the browser.

Perhaps some kind of outdated crypto situation in the NewsBlur stack…?

That means the feed is forbidding NewsBlur from fetching it. You’ll have to reach out to the publisher and ask that they add NewsBlur feed fetchers to their allow list.

Ah okay, thanks for the quick reply.

I wonder if it’s user agent based or IP based filtering… Is there a list of IPs / IP blocks used by the production feed fetchers?
