`Unable to Read Header Len > read tcp` 这个是什么原因导致到的呢

[zhang-shengping]

我的 client 是个 Mac，v2ray 版本是：

➜  v2ray-macos-64 ./v2ray -version
V2Ray 4.31.0 (V2Fly, a community-driven edition of V2Ray.) Custom (go1.15.2 darwin/amd64)
A unified platform for anti-censorship.

使用 v2ray 连接时好时坏，但是每次连不上的时候都会遇到这个提示， Unable to Read Header Len > read tcp

网上查了很多，有的人说是 NTP server。我配置完 client，server NTP 还是会时好时坏。

Unable to Read Header Len > read tcp 这个提示到底是什么意思，为什么会这样呢？
