I think I’m through the worst of it…

As you can see from the screenshot, I’ve managed to get Discourse “installed”. But I can’t seem to get a valid SSL cert assigned.

For the record I’m routing this through my Synology NAS with a reverse proxy elevating port 89 to 443 with websocket and port 89 and 449 (mapped to 80 and 443 respectively in the app.yml)

As far as I can tell, I’ve done everything I was meant to, in order to get it all set up.  
I have a certificate pointed to **[subdomain.domain.com](http://subdomain.domain.com)** but it still resolves to **[domain.com](http://domain.com)**,

Your help is greatly appreciated 🙂
