2.0版本报错：panic: runtime error: slice bounds out of range

模式是CDN模式，直连模式没有出现过这个问题

我也是这个问题，具体错误如下。
但是同样是美国的另一个vps，线路比这个还差，没有这个问题。
从日志上看，我估计当该vps线路较差，丢包率等问题导致连接中断，中断次数多了以后某个固定大小数据结构溢出导致了这个问题。可能需要考虑国内恶劣的网络线路，放宽这个限制或者不限制该数据结构的大小，哪怕因此造成最后client崩了，也比现在很快就崩了无法联网要好得多。大家用这个更重视稳定性，网速，对于内存等资源占用没那么在意的。

把cf://协议换成ws://直连服务器能成功吗

[starwar6160]

能成功，不再几分钟就崩溃，但也失去了CF的加速作用。。 Coyove <[email protected]> 于2020年9月5日周六 上午10:28写道：

确实是几分钟就报错了

[coyove]

看来cf启用了permessage-deflate的ws压缩标准，导致以前写的ws解析代码出错了。

[sunhf-git]

permessage-deflate的ws压缩标准

有什么办法能避免这个问题吗, 仍然想继续使用cdn.
