I try to set disable-server-config to true, but get fatal at core.QueryIp:L108

After checking the code logic, I found the reason is DOESN'T do a request to /por/rclist.csp

So there are two solutions:

• remove this flag, always set disable-server-config to false
• do a useless request to /por/rclist.csp even set disable-server-config to true

使用 main 分支的最新代码无法复现此错误。

运行平台 Windows 11 x64，参数为 -username xxx -password xxx -disable-server-config。程序正常运行。

在 ParseResourceLists 函数的此行

res, ok := ParseXml(&ResourceList, host, config.PathRlist, twfID)

设置断点，断点未触发，说明没有执行对 /por/rclist.csp 的请求。

补充问题： 网络环境为玉泉有线网，rvpn.zju.edu.cn解析出ip为10.3.1.170，可以复现出此问题，尝试切换热点，rvpn.zju.edu.cn解析ip为61.175.193.50，未复现此问题，或许是校方内网与公网部署的服务端有差异导致

补充问题： 经测试，ZJUWLAN、手机热点均可正常设置server为10.3.1.170, 218.108.88.254, 61.175.193.50，但有线连接三者均出现上述问题，暂时判断为本地有线/校园有线网设置问题，不影响整体的使用，关闭问题
