Running hass.io 0.71.0 on a Pi3 and have found that following power outages, the web interface is inaccessible once power is restored. I can log in via ssh without issue and browse the shares using samba.
This only seems to occur when the power fails and hass.io starts faster than my router re-establishes it’s internet connection. If I toggle power to the Pi without disturbing the router, everything starts up just fine.
This issue also occured in previous versions of hass.io
I have this problem aswell, and has come to the same conclusion. Only happens when the Pi starts faster then the router.
Where you able to find a solution?
Unfortunately not.
In my situation it made more sense to power the pi and router from a cheap UPS. That way during outages I still have internet for my laptop
