问题#

Nginx 反代飞牛用标准的反代方式之前用的都一切正常，但是最近使用了飞牛影视，发现一直播放失败，控制台查看日志发现有416的错误，使用飞牛的地址直接请求是正常的，原以为是使用了CDN的原因，准备开喷了都。遂想着顺手排查一下是不是Nginx配置的问题，使用一个没有CDN的地址，发现还是416，这就很奇怪了，这误会了，是Nginx的锅，不是CND的锅。 直接请求飞牛返回的是206，而Nginx返回的是416。

问了一下AI说是 Nginx 没有正确地处理或传递客户端的 Range 头信息。 需要添加如下配置

    proxy_set_header Range $http_range;
    proxy_set_header If-Range $http_if_range;
    proxy_buffering off;

配置完飞牛的完整配置如下
