Perhaps don’t make your CDN address `discourse-cdn.example.com`, since I’m guessing you don’t own that domain?

Port 3000 is not supported, in fact, no custom ports are supported for a production (non development) install. You have a broken install.

you say you have to install it again, or would suffice to change the port on app.yml , and apply a rebuild.

You should probably wipe the database:
```plaintext
rm -rf /var/discourse/shared/standalone/postgres*
```
