Failed to fetch available software from the Poly Hosted server

[RobA7]

I am getting the following message on all VVX phones that I manage. I've tried to talk with Poly support and they tell me that something in our firewall is blocking port 443. Well that would be ok, except that I am talking hundreds of phones across 50+ sites, some with no firewall (for troubleshooting purposes). Bottom line is, this is not a firewall or a port blocking issue and it just started sometime in the past 3 days.  We are able to fetch software on our E-Series phones no problem, but any VVX phone doesn't allow it. Any help would be appreciated. We have talked with Poly support and have gotten no where. 

Message: 

Failed to fetch available software from the Poly Hosted server. Please try again later or contact your Network Administrator if the problem persists.
