Cannot get to Open Exchange software

I learned about the Open Exchange tab here at Intersystems. I wanted to look at one of them, but when I clicked it, it tried to go to the site, then brought me back to openexchange.intersystems.com.  I then saw a "not secure" icon in the browser bar. I tried this on IE, Chrome, and Firefox, and could never seem to get into the site to look at the site https://openexchange.intersystems.com/package/Cach%25C3%25A9Quality.

NOTE: seems to affect only the link above.

Am I missing something? Is there a special setting I need to set to see these ideas?

Thanks,
