ios - stopVPNTunnel 没有断开 iOS 中的 VPN 连接

Question

我已经实现了一个成功的 vpn 连接。但是当我在连接 VPN 时关闭并打开应用程序时，我无法断开 VPN。

public func connectVPN() {
    //For no known reason the process of saving/loading the VPN configurations fails.On the 2nd time it works
    Log.d(message:  "connectVPN")
    NSLog("ConnectVPN")
    self.vpnManager.loadFromPreferences(completionHandler: self.vpnLoadHandler)
    NotificationCenter.default.addObserver(forName: NSNotification.Name.NEVPNStatusDidChange, object: nil , queue: nil) {
        notification in
        let nevpnconn = notification.object as! NEVPNConnection
        let status = nevpnconn.status
        self.vpnDelegate?.checkNES(status: status)
    }
}

public func disconnectVPN() ->Void {
    Log.d(message:  "Disconnect VPN Called")
    Log.d(message: "Log Disconnect VPN Called")
    
    print("vpnManager:disconnectVPN \(self.vpnManager.connection) ") // object available
    
    self.vpnManager.connection.stopVPNTunnel()
}

我不知道为什么它没有断开连接。

调用stopVPNTunnel()内部loadFromPreferences闭包。

NEVPNManager.shared().loadFromPreferences { error in
  assert(error == nil, "Failed to load preferences: \(error!.localizedDescription)")
  NEVPNManager.shared().connection.stopVPNTunnel()
}
