Did you ever fix this issue of failed firmware updates?

@Edwin_Tek Was wondering if you ever found a solution.  We do pretty extensive Geo-blocking on our firewall, so I suspect that, but I can't find a list of URLs needed to update these devices online.  We will take the time to packet trace and filter through the firewall logs to try to find the block, but I was wondering if someone had gotten a list from support.
