Public feed isn't accessable from the public net

[GeekAnnoyed]

Hello,
I've just been playing with the ttrrs package and it's awesome but I've found a bug/feature
The feature for shared public feeds isn't' publically accessible due to the nature of yunohost and the protection for services it offers.

you can find this setting under https://example.com/ttrss/prefs.php and then feeds> Published & shared articles

https://example.com/ttrss/public.php?op=rss&id=-2&view-mode=all_articles&key=mysecretkey

I've no idea how to debug this sorry.

after some research, I found that this command fixed it for me
sudo yunohost app setting ttrss skipped_uris -v "/public.php"
sudo yunohost app ssowatconf
this seems to have allowed access to the public URL
