Start by reproducing the Tencent Video playback failure on Linux with AnyProxy v3.10, comparing the POST /app request to news.l.qq.com against the provided Fiddler capture and reviewing issue #158. Done means identifying the proxy-handling difference and confirming that Tencent Video plays normally through AnyProxy.
