Hi Eric.
I'm having issues connecting to my git (bare metal) installation of TT-RSS (not Docker).
When I visit https://ttrss.mydomain.com/plugins.local/freshapi/api/greader.php, I see 'OK'.
But when I attempt to connect, Reeder says 'Login Failed. The requested page was not found on the server. Please verify the URL and try again.' And NetNewsWire says 'Network Error. Try again later'.
I have, of course, followed your instructions for enabling the plugin.
What may I be doing wrong?
