I added some code to my Hassio just now, clicked the check config button, all ok. I then clicked restart and it warned me on the home screen there was an error so it would restart. The error was:
Log Details (ERROR)

Hass.io config check API error
Never seen this before, so googled it. People said it was to do with the ssh, so I clicked the hass.io on the left side with the aim of reseting duckdns, but i got this error when clicking on the hass.io button on the left:
Unable to load the panel source: /api/hassio/app/entrypoint.js.
I havent changed anything for days and its been working fine. In fact now its working fine and lets us log in, I just cant restart it or make any changes.
