Got it, thanks.
Can we try setting a different DNS in Windows to see if that makes any difference at all? In some cases using a different DNS has helped with issues like this. You can update the DNS through the Windows TCP/IP Settings. For more information on how to get there check out the Microsoft Support website.
I usually go with the public Google DNS (Primary DNS: 8.8.8.8, Secondary DNS: 8.8.4.4), but if there's a different DNS you would rather use instead that would be OK as well. Let me know how that goes once you've had the chance to give it a shot.
Thanks again,
