尝试启动 openvpn 客户端时出现以下错误：
Tue Nov 28 15:28:03 2017 us=942328 OpenVPN 2.3.14 arm-poky-linux-gnueabi [SSL] [LZO] [EPOLL] [MH] [IPv6] built on Sep 6 2017

这不是防火墙问题，因为我已停用该功能以确保安全。我在另一个 ARM 客户端上使用了相同的配置，并且正常运行。
这是配置文件：
dev tun
tls-client
remote myRemoteIP 1194
pull
proto udp
script-security 2
ca /etc/openvpn/ca.crt
comp-lzo
reneg-sec 0
cipher AES-256-CBC
auth SHA1
auth-user-pass /etc/openvpn/auth.txt
log-append /var/log/openvpn.log
verb 9
知道哪里出错了吗？谢谢
