Why Slack Doesn't Allow Subscribing to the Hacker News RSS Url?

Question

I tried to subscribe using the `/feed subscribe https://news.ycombinator.com/rss` command, but Slack says "That feed (https://news.ycombinator.com/rss) could not be saved. Try again?". What happened?

Use https://hnrss.org (customizable HN feeds) and https://feedbin.com (a full featured open-source reader).
