DuckDNS remote access other than port 443 Letsencrypt

Hey guys, love the software, first post…

i have Letsencrypt installed and setup on my unraid box. I have port 443 forwarded to Unraid to handle Sonaar, Radarr, etc, and i don’t want to mess with it.

How do i get Home Assistant to work on another port? I am trying to get the Smartthings integration working and it needs the webhooks with duckdns working. In my router, i forwarded port 445 to Home Assistant Ip and it seems to work… When i try the Smartthings integration, it just looks for, not the Any way to fix this?
