FQDN needed for subscription check

[Dale.Sykora]

We are in US and recently restricted non US internet access from our network. Now our Proxmox nodes report invalid subscription status. We have added exception for enterprise.proxmox.com, forum.proxmox.com, www.proxmox.com, and shop.maurer-it.com which allow access to those sites, but still cannot check subscription status.
What other FQDNs are needed to allow subscription check from nodes?

Please try the following command:

pvesubscription update --force

Thank You Moayad! By running that command, I realized that it was trying to reach shop.maurer-it.com but still failing. I found a mistake I made in our firewall config, and after fixing the error, it worked as expected.
