Current Behavior

这是我的一级代理日志，kcp用38080端口，ftp客户端在握手时，代理日志出现WARN handshake fail, ERR: new methods request fail,ERR: timeout

Possible Solution

Steps to Reproduce

1.在112启动ftp服务端
1.在32启动一级代理
1.在31启动二级代理
1.在111启动ftp客户端
客户端 连接超时

Context (Environment)

  1. proxy version is : v12.4
  2. full command is :proxy socks -t kcp -p ":38080" --kcp-key mypassword
  3. proxy socks -t tcp -p ":8083" -T kcp -P "x.x.x.x:38080" --kcp-key mypasswor
  4. system is :win7
  5. full log is: 上边已提交
  6. ftp服务端使用FileZilla0.9.41
  7. ftp客户端使用FileZilla3.14

Detailed Description

用kcp支撑socket5代理，连接ftp时，出现连接超时
