License Won't Activate

I’m having trouble activating my license on my “host’s” Server. I get the following error:



Error: Unable to check your license number



Does anyone know why it’s not activating?? I need to activate before i can do a store import.



I didn’t have any issues on our own internal server, while I was testing V4 and converting our theme and all our addons.



The hosting company thinks that the connection shouldn’t be getting blocked, but what else can it be??



Please help.



Thanks
