Gnus RSS feeds with SSL

[Spenser Truex]

I'm on 27.5.
I've been trying to get RSS feeds in GNUS to work. Some feeds do work,
but others do not. I suspect that SSL might be the culprit. Here is an
example of an RSS feed that will not catch:
https://www.reddit.com/r/lisp/.rss

I get the error "No feeds found for https://www.reddit.com/r/lisp/.rss";
when doing G R in the group buffer.
I tried making the group first, then entering it and providing the link
then, but this fails with the error: "Group nnrss:my-group-name contains
no messages"

I did manage to get some plaintext feeds to work though. Is it that Gnus
doesn't support these?
