为什么连接要关闭？

Question

我已经安装了开放VPN。无论是在我的服务器上还是在我的电脑里。我认为我的日志文件是：

Aug 18 18:37:52 ubuntu openvpn[27920]: Local Options hash (VER=V4): 'bd6dea9e'

Aug 18 18:37:57 ubuntu openvpn[27931]: Exiting

我想知道问题在哪里，这使得VPN需要重新连接。请注意，文件ovpn.key位于当前目录中！但它仍然显示了cannot open file错误信息。

有人能说出我在哪里犯错吗？

提前谢谢。

• 始终使用绝对文件名，而不是相对文件名来引用您的密钥！
• 如果仍然无法工作，请检查文件权限。
