title: Shadowsocks Proxy error: (7) Unable to receive initial SOCKS5 response
body: <p>I am using a Shadowsocks server on my EC2 instance, and my client is a physical device (thinclient). Both use Amazon Linux 2.</p>
  <p>When I test the authentication between my client and my server, I get this error:</p>
  <blockquote>
  <p>[Thinclient]# curl --socks5 localhost:1080 ifconfig.io</p>
  <p>======&gt;curl: (7) Unable to receive initial SOCKS5 response.</p>
  <p>[server]#less /var/log/messages</p>
  <p>======&gt;getpeername: Transport endpoint is not connected</p>
  </blockquote>
  <p>Both configuration files on the client and the server are fine!</p>
  <p>Has anyone had the same issue with Shadowsocks? Do you have a solution for this?</p>
