So I installed homeESP on a HA instance that run on a VirtualBox in windows 11 on an old-ish desktop.
It worked nicely, and I started generating the firmware for an ESP device. It appears that was a bit much to ask so it crashed the computer that the VirtualBox ran on. Opun starting it up, the url http://homeassistant.local:8123/ that I previously used to acces HA now returns nothing (“this site can’t be reached”). The observer url also returns the same.
The command line tool for HA is live, and I can interact with HA with it. Amongst other things, I used it to restore my backups from before installing HomeESP, but it did not help.
I did some further investgation and finaly decided to kill the thing entirely and start over from a backup. Mostly I just wanted to say thanks for your answers
