VPN has blocked a site I use all the time. How do I unblock it?

When I type www.pickmypostcode.com the screen shows it cannot be reached. Blank screen with error message. I switched off VPN and it went to the site.
So, VPN needs to unlock this site.

AVG support must have unblocked the site www.pickmypostcode.com because it is working ok now.
