Hassio was running perfectly on my Pi up until a few weeks ago. The Pi is no longer showing up in the router while being connected with a cable. I cannot access the Pi anymore.
Is there another solution apart from starting all over again?
If restarts after power-off and network connectivity - tests without success, hard- or software seems to be broken. Easiest way for me would be to to create a new hassio - image on another appropriate SD-Card , reload your last snapshot - backup and see what happens. Backups in hass-io is essential and really easy. All should last less than one hour.
