对nginx的curl请求：拒绝alpine docker映像Recv失败：对等方重置连接

我正在尝试调试为什么我发送到docker容器的curl请求在我的Ubuntu20.04机器上被拒绝。我正在运行股票

nginx:alpine

然后我尝试向容器发送一个请求

curl http://0.0.0.0:8081/
curl: (56) Recv failure: Connection reset by peer

我曾在更复杂的图像/容器上遇到过这种情况，但这似乎是一个最小的可复制示例。通过更复杂的示例，我确保绑定到容器内部的

0.0.0.0

，而不是

127.0.0.1

/

localhost

对于未来有这个问题的傻瓜（比如我），这是由我的VPN造成的

一旦我的VPN关闭，一切正常
