Description

你好，我是在应用内先调用 VPN sdk连接vpn,然后使用FileDownloader下载远端内网服务器的文件，报 socketTimeout。

登录验证都是成功的，也是走vpn访问的远端内网服务器。请问FileDownloader不是走的应用内网络隧道吗？

Research direction

Start with the reported stack path through FileDownloadUrlConnection.execute, ConnectTask.connect, and DownloadLaunchRunnable.trialConnect. Reproduce a download after the application connects to the VPN SDK, then determine whether the timeout occurs because FileDownloader does not use the VPN route; done means the cause and supported behavior are established.
