I use the shadowsocks and the proxy client is called Trojan-Qt5. I am testing whether I can visit www.google.com in terminal.
when I set the environment variable http_proxy to http protocol
export "http_proxy=http://127.0.0.1:58591"
the command curl -Iv www.google.com return normal response.
However, when I set http_proxy to socks5 protocol
export "http_proxy=socks5://127.0.0.1:51837"
it returns
curl: (52) Empty reply from server
I just want to know why changing to socks5 protocol lead to the problem?
By the way, the question is different from this.
