RSS feed not showing up

Hi, this is probably a total noob question. (I’ve searched the forum, please point me to a previous thread w/answer, if I’ve missed it!)

I’m using this url:

https://forum.sundayschoolwinesociety.com/latest.rss

but nothing is showing up; I’m getting this message.


Any help or thoughts would be appreciated!

The forum appears to be private. Maybe that’s why?

Aaaaah. Yes, it is private but Wordpress site I’m trying to use the RSS feed for is part of the same private membership community—they share a SSO. Shoot! Wonder if there is any way to make it work…???
