Hmm.. I checked yesterday in my browser what's the security status of a connection to havelock, and it said 'this site is not secure'? (Opera on Linux) Despite connection beeing 'https'. Has this something with them beeing behind that cloudfare?
Looks fine on Win 7 Chrome for me, its possible that your browser doesn't recognise the issuer (CA) for the certificate they are using.
Cloudflare shouldn't cause any issues with SSL if its setup correctly, which it seems to be.
Here's what I see in Chrome
