转换设置

http://localhost:25500/sub?target=clash&new_name=true&url=https%3A%2F%2Fservice-6tjm1nze.trafficmanager.net%2Fsub%3Ftarget%3Dclash%26url%3Dhttps%3A%2F%2Frelaysub.trafficmanager.net%2Flink%xxxxxxxxxxxx%3Fsub%3D1%26extend%3D1&insert=false&filename=test.ini&emoji=true&list=false&tfo=false&scv=false&fdn=false&sort=false&udp=true

复现步骤

连接没有问题，但是request返回了500，本地curl能够正常拿到订阅文件。

本地curl-7.74正常:

强制http1.1也正常

期望结果

正常拿到订阅文件

实际结果

订阅失败，request服务器返回500

某些时候，有些订阅提供者会根据请求头屏蔽部分请求，subconvertor带有SubConverter-Request和 SubConverter-Version的请求头，而且目前似乎没有提供更改请求头的方法，目前好像无解。 或者你可以自己修改源代码然后编译。

确实是请求头的问题，我Fork了项目把请求头代码注释掉了，然后用Actions构建了Mac和Win的程序(Linux的构建失败): https://github.com/jing332/subconverter/releases

~~我也改了一波用Action编译了，包含Linux的，自己用似乎是可以了。~~
用修改后版本现在也还是出现一样的问题了

我也遇到同样的问题，subconverter显示"The following link doesn't contain any valid node info"，本地浏览器可以正常拿到文件，希望能解决这个问题。

遇到了同样的问题，某些服务商过滤了带有SubConverter-Request header的请求，希望能够提供一个配置让subconverter获取订阅的时候不带上这个header
