我的机器上的 VPN 客户端经常断开连接（每小时 2 或 3 次）。我使用的客户端是 FortiClient VPN 和 Cisco AnyConnect VPN。
FortiClient 的日志文件如下，

在 Windows 事件日志中出现以下消息，
Connectivity state in standby: Disconnected. Reason: Policy Setting
7026 - Dump after return from D3 after cmd
The system is entering connected standby. Reason: Idle timeout
断开连接时我并没有长时间处于闲置状态。对我来说没有互联网连接问题。
