Hi. I just did a hassio ha restart after making some changes and now Home Assistant is not starting up. I can ping the server, but the UI never becomes available, and I can’t ssh onto it. Has anyone got any idea what could have happened? I’m pretty sure that config changes couldn’t have made this happen.
If I plug it into a monitor I get this:
I don’t know if it’s correct or not as I’ve never plugged in a monitor.
Thanks.
Actually it 100% can make that happen. You need to look at the log file and see why it’s not starting, but my guess is that you have a syntax error on your config.
Unbelievable. 
I had a block of yaml commented out, then just did Ctrl + / to uncomment, assuming that it would still be indented correctly. The block was 1 space out.

I should have known to look at the log. 
Thanks for your help.
