Did you rebuild after you changed the value? ([Enable a CDN for your Discourse](https://meta.discourse.org/t/enable-a-cdn-for-your-discourse/14857), which is linked to in the `yml` file you edited says to rebuild after the change.)

No, what needs to be done is to do a rebake of the posts to fix the references to the old CDN. See [Disable CDN causes old images with CDN URL can not be shown - #2 by zogstrip](https://meta.discourse.org/t/disable-cdn-causes-old-images-with-cdn-url-can-not-be-shown/29657/2) for two ways to do it. The simpler way is:

```plaintext
# ssh into server
cd /var/discourse
./launcher enter app
rake posts:rebake

```
