ssl.SSLError: [SSL: DECRYPTION_FAILED_OR_BAD_RECORD_MAC] decryption failed or bad record mac (_ssl.c:2635)

使用get_series 下载的时候经常会报这个错误，调低并发数也会报同样的错误。
使用get_video下载报错的单个视频时，没有再报错。
下载命令如下，不不知道能不能复现：
bilix s https://www.bilibili.com/video/BV1hS4y1m7Ma --dir /mnt/e/tmp --subtitle --max-con 20

异常信息如下：

我尝试执行了

bilix s https://www.bilibili.com/video/BV1hS4y1m7Ma --subtitle --max-con 20

在我这边网络条件下完整的下载下来了🤣，你或许可以使用--max-con 1来最大限度避免未知的网络错误，分段并发数以及音画异步下载仍然能保证较快的下载

我注意到，错误信息中出现
/home/liy/.local/pipx/venvs/bilix/lib/python3.8/site-packages/httpcore/_async/http11.py
这说明HTTP/2协议没有启用，这个可能是报错的原因，<-b站的后台确实有时候以http1.1接受请求，所以不是这个问题

那这个issue先关了吧，不容易复现
