New hass.io - started but now i cannot connect

I just set up my raspberry pi hass.io

First time I connected fine. I added some add-ons (samba, control panel, configurator (though it won’t start), etc).

All fine. Then i tried to change passwords (both in the configuration.yaml and in secrets.yaml

Then restarted…was asked for password…wasn’t correct (apparently).
I’ve restarted again but now cannot connect via browser. (“ERR_CONNECTION_REFUSED”)
But I can see the hassio on Samba and can open and edit files.

Not sure what’s gone wrong.

I’m having a similar issue.

Can you open your home-assistant.log in the config directory?
