No Internet message when trying to access git.settuk.com

Since I installed the latest version of Norton 360 for Mac I can no longer access one particular website ... git.settuk.com ... with or without VPN active.

I can't see any firewall rules specifically blocking it.  I tried entering a specific rule to allow access.  Any ideas??

I assumed that the problem here was at my end.  It turns out it wasn't and I now have access.
