Plese fill the template when you reporting a new issue, thanks!

#### Which platform are you running AnyProxy

windows

#### The version of the AnyProxy

4.0.12

#### Your expected behavior of AnyProxy

能连上代理

#### The actual behavior of AnyProxy

手机和电脑在同一个wifi下，并且已经确认连代理的ip和端口是正确的，但是真实的情况确是连不上代理，anyproxy启动之后，控制台没有任何输出。

#### The log of the error

连不上代理，无日志

Start by reproducing the report on Windows with AnyProxy 4.0.12, using a phone and computer on the same Wi-Fi network. Check whether the proxy is listening on the reported IP and port and whether the console produces any output. Done means the phone connects successfully or the failure is narrowed to a concrete error with captured logs.
