reason:
When the network is relatively poor, the data channel request agent, without waiting for the proxy server to return a message, and processes. Then send the SSL certification, lead to authentication failed.‍‍


scheme:
Data channel using delay.‍‍


modify:
file:http_proxy.c;
function:‍Curl_proxyCONNECT‍
line:231~239
The red word for new added code‍
    check = Curl_timeleft(data, NULL, TRUE);
    if(check <= 0) {
      failf(data, "Proxy CONNECT aborted due to timeout");
      return CURLE_RECV_ERROR;
    }
    if(FIRSTSOCKET == sockindex) {
      if(0 == Curl_socket_ready(tunnelsocket, CURL_SOCKET_BAD, 0))

        return CURLE_OK;

      }
    }
    /* at this point, the tunnel_connecting phase is over. */
