www.cloudy2clearwindows.co.uk will not load in safari but will in chrome

Hi

http://www.cloudy2clearwindows.co.uk will not load in safari but will in chrome?

I get the error attached

This only happens in safari? What does the error code mean? I have cleared cache and everything. The site works in safari on my iMac but not on this machine (MacBook pro).

any way i can reset safari maybe?
