I have installed duckdns, now i have https://192.168.x.x:8123 and a red line on https
and i can’t enter Home Assistant from mydomani.duckdns; is that for my ip natted or I’m missing some configuration?
I’m running Hass.io 0.87 on ubuntu 18.04
This is because the SSL certificate is for your duckDNS domain/WAN IP address not your local IP address. You can ignore the warning or install a reverse proxy like Caddy or Nginx.
When you go to your duckDNS configuration web page does it report the correct public IP address of your router?
If not your ISP may be using CGNAT and that is going to be a problem.
If the addresses do match you have some other configuration issue. e.g. Have you forwarded the correct ports in your router?
i have this on the duckdns

And this in the router

Yep your ISP uses CGNAT. Give them a call and ask if you can be assigned a non NAT’ed address for remote access to your network. I had to do this and they did it no problem (and free of charge).
