NACHI energy report shows bogus site

I just tryed to produce a home energy report, when I went to this site: https://energytool.nachi.org/

I get a warning that I am trying to go to a potentially harmful site that is not really nachi.
Could I get a little help here?

Am I the only one having this problem?

Now it is working ok… That was strange.

I just clicked on it and got the warning page. Something IS messed up. Copy and pasted page below…

There is a problem with this website’s security certificate.

Hi guys,

It looks like you’re trying to load a secure version of the site, via HTTPS. Just go to:

…and you should be fine.
