Connecting to HA externally - Unable to connect to Home Assistant

use the dns server from your router to ‘spoof’ your (duck)dns name internally…

HTTPS inside LAN | New Version of HA iOS App

Yeah, you are right… what I did: added a domain name in my router f.e. assistant.url [image] added a lease for HA on it’s IP f.e. 192.168.100.100 and gave it a name f.e. home [image] After that, your router should be able to resolve home.assistant.url as the reserved IP (home.assistant.url should equal your qualified https dns name )

No need to forward both 8123 and 443
When you use http forward port 80 to 8123 and use http://my.domain.dns/
When you use https forward port 443 to 8123 and use https://my.domain.dns/

(or just forward port 8123 only and use
http://my.domain.dns:8123/ or https://my.domain.dns:8123/)
