When I’m home (local network), I only can access my HA with the external url address !?
Secondly, I wonder if the yellow should be added or not… ?
Thank you for the link, but it’s a lot of Chinese for me 
I installed HA on an Odroid N2+ device (so Home Assistant OS). I installed the DuckDNS add-on and did the configuration.
My router has a correct WAN-IP (213.x.x.x) and I did a port-forwarding of port 443 (port 80 is for my peha system) :
Test :
And in my configuration.yaml :
Did I do something wrong ? The document is talking about NGINX add-on, do I need this ?
If you need other information, let me know.
Thanks for helping me !
Please note - providing images of text is incredibly unhelpful to anybody who doesn’t have the same vision as you. Whether that’s somebody who uses large print, a screen reader, is colour blind, or whatever… it makes it harder for us to help you.
Yes, you’ll need the NGINX add-on if you want to use http: for the internal URL You can use https:// for it currently, eg https://192.168.1.6:8123/
Sorry, I hadn’t thought of that. My intention was to provide you with as much information as possible.
Thanks for the info!
Were you able to make it work?
I didn’t change it after all.
Everything works fine like it is, so I don’t want to destroy something…
