我已经在 Ubuntu 18.04 上安装了 OpenVPN 社区版。连接 OpenVPN 后，我无法连接互联网和其他网站。请检查我的Client.conf和Server.conf下面的内容，并告知我是否有任何问题。

此外，当添加up/down update-systemd-resolved并尝试连接 OpenVPN Connect 时，即使脚本存在于相应的文件夹中（/etc/openvpn/scripts）错误，也会出现以下错误：
Options error: --up script fails with '/etc/openvpn/scripts/update-systemd-resolved': No such process (errno=3)
Options error: Please correct this error.
Use --help for more information.
您能指导我如何修复此问题吗？使用 OpenVPN 和互联网连接。
