启动的时候 Sorted latencies: 570.0917ms socks5://127.0.0.1:28080 怎么到后面就 no valid proxy socks5://127.0.0.1:28080 在别的软件测试过是正常。

原因如 readme 所述：

使用相同协议的上游代理原始请求。

即不做代理协议的转换。


2023/09/13 03:36:47 [http] CONNECT translate.google.com:443 <- 127.0.0.1:4484 [type:0]
2023/09/13 03:36:50 [http] direct:1/1 CONNECT translate.google.com:443 <= dial tcp 142.251.42.238:443: i/o timeout
2023/09/13 03:36:50 [http] proxy:1/3 CONNECT translate.google.com:443 <= no valid proxy

表明，下游程序选择了 http 代理协议，而你没有提供上游 http 代理。


解决方案：

  1. 推荐，同时设置上游 http 代理和 socks5 代理，可多个。下游程序根据需要自己选择使用哪个协议。
  2. 或者，只给下游程序设置 socks5 代理，不设置 http(s) 代理。
