This is the initial step to use the Wireguard/DuckDNS, already installed, and it already worked once. (the day i have deployed and tested). Now that i want to pickup again this got this issue :confused:

If i try to connect trough homeassistant.local on my mobile got the “can’t resolve name server”

Any ideas?
