We're Unable to Establish a Connection error message

CCleaner recently added "Health Check". Every time I try to do the Health Check, I get the error message, "We're unable to establish a connection".

PLease help if you can.

Lots of reports on forum about this, here are some.

As yet there has been no comment about this from Piriform.
