“Remote Peer Disconnected” or “Rejected” could mean a number of things but the number one culprit would be your firewall or router. To fix this, you’ll need to contact your VPN and find out the ports that need to be bypassed by the firewall or the operating system. If this doesn’t fix it, determine if the router is the culprit by unplugging the internet feed from the router and plugging it directly into the computer, thereby creating a single internet user. If the Remote Peer message goes away, the problem is the router. Typically, your VPN’s tech support would talk you through a complete troubleshooting routine.
