Chatgpt (codex) and some other apps not working

application like Duolingo, and codex isn't working even I connected my vpn. I think that it still detects my location that I'm in china, is there a fix for this? I can access Duolingo with other free vpn from my phone, but codex is important for my work and I need to access it from my Mac, and I only have Geph vpn. please I need solution, I have tried connecting to other server but its also not working.

1、分流隧道,关闭排除大陆流量。。。如没有打印机、智能家居,关闭允许访问本地网络。
2、IPv4下的VPN可能不如 IPv6下的代理模式。。。开启自动配置(系统)代理。。。

他山之石可以攻玉,参考:迷雾通V5.8+版本Win电脑、安卓手机的基本操作

前有 Battery drain & overheat IOS (上帖:苹果手机:u7981:VPN模式用代理模式)还不能融会贯通、触类旁通。。。(本帖:苹果电脑:u7981:VPN模式用代理模式)

分流隧道,排除大陆流量:或开(上帖)或关(本贴),具体情况,需要灵活运用。。。

3、如坚持全局VPN模式,参考:

实质就是,迷雾通已打开连接的机器重启、冷启动能100%虚拟网卡创建成功,系统登录后的打开连接,则未必:报错、断网、或一直连接中。。。即使连接上,较慢、不稳。。。
