無法完成您電腦與 VPN 伺服器之間的連線。最可能的原因是您的電腦與 VPN 伺服器之間，至少有一個網際網路裝置 (例如防火牆或路由器) 並未設定為允許 Generic Routing Encapsulation (GRE) 通訊協定封包。如果問題持續發生，請連絡您的網路系統管理員或網際網路服務提供者。

The VPN connection between your computer and the VPN server could not be completed. The most common cause for this failure is that at least one Internet device (for example, a firewall or a router) between your computer and the VPN server is not configured to allow Generic Routing Encapsulation (GRE) protocol packets. If the problem persists, contact your network administrator or Internet Service Provider.
