thanks very much.
that’s really bizzare…what could / would have changed permissions?
I also noticed that with /srv/homeassistant/bin there was no hass file, so I could not restart it.
having added the file from a previous backup it I was able to start home assistant again.
Ok, so I upgraded and nnow have lost home assistant altogether…

A regular, non-root user may not start a TCP listener on ports < 1024. You must run HA as root, if you want it on port 80, however that is not recommend.
It’s better to run HA as dedicated user on port 8123 and use a proxy like nginx to expose HA on port 80/443.
