/feed redirecting to homepage

I’ve got a wordpress installation at https://stadivm.com/cc and when I go to https://stadivm.com/cc/feed it redirects to https://stadivm.com/cc.

The rss feed isn’t showing up in any rss detectors because of this, however when I just the plugin Fix My Feed RSS Repair is shows that it is working at https://stadivm.com/cc/feed (although then when I click on it it still redirects).

Any ideas about what’s going on?

I’ve got an nginx redirect that might be the culprit:

location /cc {
index index.php;
try_files $uri $uri/ /cc/index.php?$args;
break;
}

Apart form that, no idea?!
