Exception: java.net.SocketException: Malformed reply from SOCKS server

Thank you for your help

Answer 1

您已将应用程序配置为使用 SOCKS 代理，但您指定为proxyAddr的 host:port 上的实体不是 SOCKS 服务器。

Answer 2

To fix this:

1) Open Tools -> Internet Options in Internet Explorer (or alternatively, Control Panel Network Settings in Windows 7)

2) Open Connections tab

3) Click on LAN settings

4) If "Use a proxy server" is enabled, click Advanced and disable "Use the same proxy server for all protocols"

Answer 3

This just controls what Internet Explorer does. It has nothing to do with Java. The OP's code is explicity use a SOCKS proxy, or trying to. Not relying on any Control Panel setting

Wrong on Windows.... Internet Options controls the way Windows use Proxyserver, Internet Explorer is just one Application that uses the "Windows Standard configuration" Java in Standardconfig uses the "Systemstandard" to connect, so if you don't specify the Proxyserver via Java this workaround will help, but it'S not a "solution".
