DuckDNS addon - Problem connecting to server (get for https://acme-v01.api.letsencrypt.org/directory; curl returned with 6)

I seem to have a problem with using the DuckDNS addon whenever i wanna use the adguard addon or pihole.

If i wanna use adguard/pihole i need to disable dnsmasq on the host cause port 53 is already in use. Whenever i do that the Duckdns addon in hass.io seems to break with the following error:

# INFO: Using main config file /data/workdir/config
ERROR: Problem connecting to server (get for https://acme-v02.api.letsencrypt.org/directory; curl returned with 6)

The pihole/adguard seems to work fine for the rest, just duckdns addon breaks. If i enable dnsmasq again, the addon will start working again. Does anyone have a idea what i can do to solve this problem?

Did you find any solution? I have the same problem trying everything without any luck.

Maybe this solution helps: ‘ha dns update’ and/or ’ ha dns restart’ on the command line in the HA environment, see also How to resolve config errors after DuckDNS.

Hi I have just installed home assistant on a raspberry pi 3, and am experiencing the same problem when installing duckDNS. Below is a snippet from the log when I startup the DuckDNS addon

I am using version 5.12 currently, having downgraded when I experience the issue with the latest 5.13 version (github.com/home-assistant/operating-system/releases/download/5.13/hassos_rpi3-64-5.13.img.xz).

My installation is very recent, only a few days old, and I simply have not been able to make this work.  I have followed numerous web links from others experiencing DuckDNS issues, but so far without any success.

If anybody can offer any tips/suggestions, they would be gratefully received
