Problems with Duck DNS after the recent update

Eversince the recent update of Home Assistant (2023.11.3). My Duck DNS configuration is no longer working. Locally I am still able to acess Home Assistant via the IP. I have the feeling it is either a problem on duckdns.org side or it is a problem with the router. I have reinstalled both NGINX and DuckDNS. In my mobile app it does detect the duckDNS adress but when I try to connect it gives me the Errorcode -8 (net…ERR_CONNECTION_TIMED_OUT). I have tried to reinstall DUCKDNS multiple times.

Further Information: The Plex Server still runs without a problem.

Some basic checks:

  1. Does your DuckDNS hostname resolve to the same IP listed in your router’s admin pages?
  2. Have you checked that the port is open?
  3. Did you check that the port is still forwarded to the IP that your proxy is on?
  4. Did you check the proxy logs?
  5. Did you check the proxy configuration is still connecting to the right IP for HA?

Hello,
Thank you for your Message! For your Questions:

  1. Can you elaborate what you mean by DuckDNS hostname ?
  2. I have double checked the Ports. My HA IP is 192.168.1.10 . I have connected Port 443 to Port 443 and Port 8123 to Port 8123.
  3. In The Settings of NGINX it is set to the default Port (443)
    4.I did check the Logs for both DuckDNS and NGINX and they dont mention any problems.
  4. Can you please tell me how I check this?
    Inside the Homeassistant Network Setting both Internal and External are set to: https://XXXXXX.duckdns.org:8123

My settings in the configuration.yaml are:

> http:
>     cors_allowed_origins:
>         - https://google.com
>         - https://www.home-assistant.io
>     ip_ban_enabled: true
>     login_attempts_threshold: 5
>     use_x_forwarded_for: true
>     trusted_proxies:
>       - 172.30.33.0/24

I also tried reverting back to my last version: 2023.8.3 but it did not help to solve the issue.

example.duckdns.org

But did you actually test to see if the port was open? That blue text is a link to a tool to help you.

And the IP of your NGINX host hasn’t changed?

They’d also tell you if connections were happening.

Proxy, not Home Assistant. Check the configuration of the proxy to see what it’s set to do.

If you don’t understand then share the proxy config - and remember to use code markup.

Thanks for all the help. I did end up switsching to Nabu Casa.
