推荐答案

您可能正在尝试通过 https 与 http-only 代理进行连接.

You are probably trying to connect via https with http-only proxies.

您可以使用在线 HTTPS 代理测试器来检查您的代理是否支持 https 或使用 Linux curl 命令使用代理 :

You can use online HTTPS proxy tester to check if your proxies support https or use Linux curl command with proxy :

curl -x http://111.222.333.444:80 -L https://myip.ht
