我有 Windows 10（操作系统版本 17763），我已按照以下步骤创建了与 QNAP 设备的 PPTP VPN 连接本文。遗憾的是，无法建立连接。在应用程序事件日志中，我可以看到以下 RasClient 事件：
Event ID 20221 - CoId={9A9B6463-F59A-4806-B201-5861E839DAC4}: The user SYSTEM has started dialing a VPN connection using a per-user connection profile named myVPN. The connection settings are....

Event ID 20226 - The user AzureAD\[my_user_name] dialed a connection named myVPN which has terminated. The reason code returned on termination is 829.
我做了以下操作但没有成功：
- 卸载 ESET Internet Security，重新启动计算机，禁用所有 Windows 防火墙，
- 成立本文在 QNAP 论坛上。应用注册表设置并重新启动计算机，
- 删除并重新创建 VPN 连接，
- 是否重置了整个 TCP/IP 堆栈
我已经在另一台 Windows 10（OS Build 17134）计算机上创建了相同的 VPN 连接，并且可以毫无问题和努力地连接。
您有什么技巧/窍门可以帮助我解决或排除该问题吗？
