Sos guys. Today, after the power outage, HA stopped working. I decided to reinstall it and then restore it from the backup.
But at the stage of installing hass.io, there was a problem.
Using the key
curl -Lo installer.sh https://raw.githubusercontent.com/home-assistant/supervised-installer/master/installer.sh
bash installer.sh --machine raspberrypi4
I am getting the following error
Failed to connect to raw.githubusercontent.com port 443: No route to host
Save what to do now, I just do not know.
