I have a line in my configuration.yaml

You're putting http://192.168.0.42:8123/ (or whatever the IP is) in the URL bar?

Browsers will default to assuming https: these days if you don't, and there's nothing HA can do about that.

yes i try to put http://xx.xx.xx.xx:8123/ (with correct ip) and it automatically switches to https://xx.xx.xx.xx:8123/

That's something in your browser
