Reboot Breaks WebUI?

I had this happen twice to me. I reboot the host system via the web GUI and I can no longer access it once the Pi is back online. SSH and Samba still work fine. I tried the restart command with the Hassio CLI and it keeps giving me the error:

core-ssh:~# hassio homeassistant restart

Any ideas?

Try deleting the home-assistant_v2.db, but it may be a sign that your SD card may be on its way out…

Thanks for the reply. I deleted the file you suggested and still couldn’t get into the web GUI. The SD card is a brand new samsung evo 32GB. Don’t think it is the card. I am using a rPi 3+ with the latest Hassio image, maybe that is it? I only just started messing around with Home Assistant, so I will just reflash the card and check to see if the reboot works on a fresh install. Then I will make sure I back everything up!

So, after a fresh install the webGUI still works after a reboot. I did use the 32bit image this time instead of the 64, wonder if that had anything to do with it? I am going to start installing add-ons now and see how it goes.

64 bit is a work in progress. For stability, use 32 bit.

It’s been about a week and everything has been working great with the 32bit version. Thanks for the help!
