I was able to modify the `/etc/nginx/conf.d/discourse.conf` file to include several `Access-Control-...` headers to avoid the `Unknown error` during log in when using SSO.

Now I want to trigger these Nginx settings via `app.yml` so that we don’t have to manually modify the Nginx config. However, when I specify the following settings in the environment section of `app.yml` and bootstrap via `launcher`, the Nginx config does not get updated.

Any idea as to what I am missing?

```
 ## Enable Cross-origin resource sharing so that SSO works properly
 DISCOURSE_ENABLE_CORS: true
 DISCOURSE_CORS_ORIGIN: '*'

```

The CORS headers are added via Rack, not nginx. The config should not be updated by adding those settings, but your site should start serving the correct headers.

Excellent. Confirmed this is the case:
