No response
我这里不能复现。
The FIN_WAIT_1 state is waiting for the peer to ACK the FIN that this end has just sent. That outgoing FIN is subject to all the normal TCP retry and timeout processing, so if the other end has completely disappeared and never responds, TCP should time out the connection and reset it as a matter of course.
可能是因为你的 VPS 请求国内的B站服务器，断开连接时服务器发送的 ACK 丢包了导致握手流程没有完成。
可以参考一下这个 serverfault 问题：https://serverfault.com/questions/7689

我放的 log 不是很好，抱歉；
重启之前是 ESTABLISHED，重启之后变成了 FIN_WAIT1；录播姬可能启动二十天了。
试一下在高级设置里把使用的网络换成 “系统”，默认应该是 “IPv4 和 IPv6” 或者 “全部” 忘了具体写的是什么了。
可以考虑之后把默认换成 “系统”。
