xl2tpd.service: main process exited, code=exited, status=1/FAILURE

[hui-QY]

大佬可以帮忙看看吗 o(╥﹏╥)o

Describe the issue
xl2tpd 启动失败

刚开始安装完是正常的，用华为手机连接测试没用题，用的 IKEv2 VPN 客户端方式连接

下午在win11上也是用IKEv2 VPN 客户端方式连接，第一次连接成功，用IP地址网站查看已经是VPN服务器的IP了，但网速很慢
google 都用不了

提示

无法建立计算机与 VPN 服务器之间的网络连接，因为远程服务器未响应，这可能是因为未将计算机,与远程服务器之间的某种网络设备(如防火墙、NAT、路由器等)配置为允许VPN 连接，请与管理员或服务提供商联系以确定哪种设备可能产生此问题,

然后在手机上也连接不了了
这是手机连接的日志

@hui-QY 你好！根据你的描述，xl2tpd 的这个错误信息可以忽略，因为它是服务退出时的正常的日志。另外在通过 IKEv2 模式连接时，不使用 xl2tpd 服务。对于你遇到的问题，根据日志中的 retransmission 等错误来看，可能是 VPN 连接被防火墙比如 GFW 屏蔽或干扰了。对于此用例，你可以另外尝试其他解决方案，比如 Shadowsocks。

@hwdsl2 好的，谢谢^_^
