Gui on : 8123 will not load now

Was setting this puppy up for the first time and repeatedly when I make graphical changes and reload HASS, the interface will not load.

What should I change in my configuration file?

I’m sure someone more knowledge will come by and give you a better answer, till then… if you setup SSH log in and take a look at home-assistant.log, should be in your config directory, should show you where the failure may be.

This is the first thing that stands out at me.

Don’t put quotes around the secret name.

Optimistic is misspelled on your mqtt cover.
