Expected Behavior

使用API认证（--auth-url）时，UDP能通过认证，且成功代理。

Current Behavior

UDP程序通信时，使用API认证（--auth-url）无法通过认证，goproxy程序直接崩溃退出。

Possible Solution

Steps to Reproduce

1.启动命令：
proxy sps -t tcp -p "111.111.111.111:1880" --udp --disable-ss --disable-http --auth-url http://127.0.0.1/auth.php --debug
2. auth.php，参照的文档中的示例：
在

使用sockscap64 测试UDP，使用标准的SK5协议
goproxy直接退出
