Error messages like "Ciiva - The underlying connection was closed...", "Ciiva - An exception occurred during a WebClient request.", and "Push notifications service was not properly initialized" infers that your organization has strict firewall rules and/or antivirus running, that some URLs and ports need to be opened or whitelisted. If there is difficulty with installing or running Altium while connected to a VPN, but disconnecting from the VPN resolves the issues, then most likely it is due to the blockage of such network traffic.
Starting in Version: 18.0Up to Version: Current
Solution Details
Sometimes when connected to a VPN, data traffic intended to go to an internet location will try to access the internet through the VPN rather than your local internet provider. When this happens, the traffic is subject to the rules and filters of the VPN. If things stop working while connected your organization's VPN, your IT support may need to unblock some network traffic. Give them this information and see if they can make a change for you.If your local area network is "hardened" (made more secure than default) it may be necessary to have your IT department open some ports and white list some website addresses to allow proper communications for the online installer, database connectivity, parts and supplier information, etc.
These addresses need to be unblocked to use the online installer and sign in:
http://appregistry.api.altium.com/
http://appregistry.live.altium.com
http://vaultinstallation.live.altium.com
http://vaultinstall.altium.com
https//prd-v3.altium.com
godaddy.com (for security certificates)
amazontrust.com (To access an On-Demand license)
And these for updates:
"vaultinstall.altium.com", "appregistry.live.altium.com", "vaultinstallation.live.altium.com", "install.altium.com", "installation.altium.com "
