Hi,

You could try something like this instead:

0.0.0.0        www.websitemanagers.com.au        # noconn 
httpstatus;https://www.websitemanagers.com.au/;2.. sni

The 2.. means any http status code starting with 2 (and two following 
characters). See the man page for hosts.cfg for the details.

In my case, any non-2xx status results in a red.

PS, I did think by default a 5xx status would be red, but not entirely 
sure why it isn't in your case. I think there is another global config 
option somewhere for that, but I've not used that option.

Regards,
Adam
