令人迷惑的400 bad request

[wl223600]

V2Ray的版本？

服务端：4.38.3
客户端：4.32.1（v2rayNG）、4.38.3（v2rayN）

你看到的异常现象是什么？

浏览器直接访问8080端口、v2rayNG/v2rayN内测试均提示400 bad request

你期待看到的正常表现是怎样的？

正常使用

请附上你的配置

客户端 "path": "/ray",
服务器 "path": "/ray_v1"
不一致

[wl223600]

谢谢提醒，之前往github里粘配置的时候忘记忘记改过来了。实际情况是客户端的path也是“/ray_v1”。刚刚服务端设置了"security" :"none"，仍然不行。浏览器直接访问地址如图所示。
（截图时访问地址是nginx反代的，但无论是否反代，都有这一问题）

[wl223600]

破案了，v2ray写了"acceptProxyProtocol": true,但nginx没写proxy_protocol，此贴完结。
