I am trying to remotely access my HA. This was working for sometime and then suddenly it stopped, i have no idea why. I am on the very latest version of HA. I have set up a subdomain on duckdns.
I then have added this to the config of duckdns addon:
As far as I know you can only access it locally with https once you setup letsencrypt and duckdns, unless you are using a reverse proxy. (which I do and also why I have the http address for the internal URL)
Let’s encrypt generates a certificate for your domain, not for your local IP. Therefore when you try to access HA through the local IP with https you get a certificate error, that needs to be ignored, because there is no certificate for the local IP.
In my opinion, it’s best to use a reverse proxy such as NGINX or Traefik. Then you can continue using http locally and avoid the unnecessary SSL overhead, but still keep SSL for remote access.
Hi! I’ve the same issue. I’ve configured duckdns, forward port 8123 ->8123. All was working fine until I’ve installed Wire Guard. Since I’ve created another port to Wire Guard, I’ve deleted the port for 8123 so I can use Wire Guard VPN instead. While connected to the VPN, outside the home network I can access my HA local IP, but I can’t access through the application nor the duckdns address. Did you manage to solve it?
