概括：Windows 10 OpenVPN 客户端在路由由 OpenVPN 服务器推送的情况下，处理路由设置时会遇到问题（但最终连接正常）。拒绝服务器路由的客户端会立即连接。
细节：我有一个 OpenVPN 服务器，用户可以从 Windows 10 机器连接。
客户端配置有两种类型：一种是服务器推送的路由被客户端拒绝（它会自行添加一些路由）；另一种是客户端接收服务器配置，包括强制所有流量通过服务器的路由。
两种配置的区别在于以下几行（位于上面的第一个配置中）
# refuse routes from server
route-nopull
# add home routes
route 10.10.10.0 255.255.255.0
route 10.10.11.0 255.255.255.0
route 10.10.12.0 255.255.255.0
从这样的客户端连接时没有任何问题，连接很快建立，没有任何错误。
在第二种情况下，连接也通过（编辑：并且连接正确并按预期工作）但途中出现错误：

这似乎是一个已知问题（已有几年了），但是仅适用于最终失败的连接（如上所述，我的两个客户端场景都连接了）。有一些深奥的解决方法对我来说不起作用（但它们都围绕着启用接口 - 在我的情况下这不是问题）。
问题似乎出在来自服务器的路由设置上。客户端设置的路由直接应用即可。

在诊断问题时，我建议首先在日志中搜索包含error/ fail/ denied/的行warning，因为它们通常最有帮助。您的日志给出了以下行：
Tue Aug 16 18:17:31 2016 C:\Windows\system32\route.exe ADD 10.10.10.0 MASK 255.255.255.0 10.20.1.254
Tue Aug 16 18:17:31 2016 Warning: route gateway is not reachable on any active network adapters: 10.20.1.254
Tue Aug 16 18:17:31 2016 Route addition via IPAPI failed [adaptive]
Tue Aug 16 18:17:31 2016 Route addition fallback to route.exe
Tue Aug 16 18:17:31 2016 env_block: add PATH=C:\Windows\System32;C:\Windows;C:\Windows\System32\Wbem

Tue Aug 16 18:17:31 2016 Warning: route gateway is not reachable on any active network adapters: 10.20.1.254
Tue Aug 16 18:17:31 2016 Route addition via IPAPI failed [adaptive]

10.10.10.0/24这意味着您的配置文件包含无效的指令，无法使用不存在的适配器创建路由10.20.1.254，这可能是旧配置的遗留问题......
