I was using a Ubuntu install with docker and after install some add ons, i notice that this happens after install duckdns add on. HA get unstable and suddenly stop to work. When try to restart HA never comes alive again. Tried to reboot ubuntu and now Debian and happens the same and the home assistant becomes unavailable. At this time it´s the third time that i´m trying to install this. But right now i will try to follow the approach to install without docker, just with python. as the steps described here.
Maybe someone already face this and have some clue what is happens.
Thanks in advance.
