DuckDNS and Let's Encrypt Addon Access via IP only

Installation Home Assistant OS
1

Hello everyone,

I’m trying to setup a secure remote access to HA but nothing is working properly. Now I can only access HA via its IP address on my network (with https://).

What I did:

  • Installed the DuckDNS and LetsEncrypt addon.
  • Entered the following in the config of the addon:
{
  "lets_encrypt": {
    "accept_terms": true,
    "certfile": "fullchain.pem",
    "keyfile": "privkey.pem"
  },
  "token": "myduckdnstoken",
  "domains": [
    "mydomain.duckdns.org"
  ],
  "seconds": 300
}
  • Entered the following in configurations.yaml:
http:
  base_url: https://my-domain.duckdns.org:8123
  ssl_certificate: /ssl/fullchain.pem
  ssl_key: /ssl/privkey.pem
  • Rebooted.
  • Yesterday the https://mydomain.duckdns.org was not working but I was able to access HA with https://hassio:8123. Today after no changes made I can only access it via https://192.168.x.xxx:8123
  • I cannot access the Pi on my network to change the config file.
  • I tried to change the IP on DuckDNS to what my router gives me as my IP, and my public IP but none of that worked.
  • Checked DuckDNS addon log, it just says “NOCHANGES OK”
  • Setup a port forwarding in my router for port 8123 to 8123 set the protocol to TCP to the IP of the Pi, and I enabled “Enable (Auto Detect Default WAN IP/Interface)”
  • I did NOT do the last change in the domain JSON settings as I was not able to find where to add the following as instructed at the very bottom of this page https://www.home-assistant.io/addons/duckdns/ :
{
  ...
  "domains": ["my-domain.duckdns.org","*.my-domain.duckdns.org"],
  ...
}

I also looked for existing posts but was not able to find a solution. Any help would be greatly appreciated.
