ETIMEDOUT on macos

• I understand project setup issues should be asked on StackOverflow or in GitHub Discussions.
• I updated to latest http-proxy-middleware.

Describe the bug (be clear and concise)

About half of the http and ws requests can not be proxy with such message
' Error occurred while trying to proxy request xxx from xxx to xxx (ETIMEDOUT) '

Yet my workmates using windows did not have such problem.

And Weirdly, When I using LAN and add headers: { 'Connection': 'keep-alive' } in config options,The problem gone!
When I using WIFI or remove the headers config, Problem returns.
It likes that http-proxy-middleware does not add headers when proxy the request

Step-by-step reproduction instructions

1. Using Macos 12.2.1 and Node 16.6.2
2. Proxy the http request and ws request in any project

Expected behavior (be clear and concise)

All the http and ws requests should be proxy successfully.

How is http-proxy-middleware used in your project?

What http-proxy-middleware configuration are you using?

module.exports = function (app) {
  app.use(createProxyMiddleware('/stomp', {
    target: backendAddr,
    ws: true,
    onProxyReqWs: (proxyReq, req, socket) => {
      socket.on('error', function (error) {
        console.warn('Websockets error.', error)
      })
    }

And I try to sniffer http packets from my node-server-ip to real-server-ip.
According the packets, the request that proxy by http-proxy-middleware connection header is closed.

Could you try on a different Mac?

[tinystorm]

Same problem.
I searched the 'etimedout in mac' in node.js issues and got some similar problems.
I wonder if it is node.js's problem?

[chimurai]

You could try it with different node versions to see if that's the case

[samelm]

Same problem.
It is solved by switching only to mobile hotspot.
But through wifi I often get timeout error.
Using http-proxy-middleware@2.0.6 in webpack-dev-server

not to proxy socket.io, then replace the https: true with ca files , would improve this problem
