Breaking change in 2.9: listening server on server.hmr.port

Describe the bug

We have a bit of a special setup: instead of Vite proxying our server, we proxy to Vite via our server. We do this using a config that has a section looking like this:

  server: {
    port: 5588,
    hmr: {
      port: 3001,
    },
  },

This makes the in-app Vite client contact a server on port 3001, and this has been working fine up until now. But with the 2.9 upgrade, suddenly Vite itself started a listening IPv6 port on server.port. This is new, and conflicts with our setup. I am not sure of a workaround.

Oh, sorry @fatso83, we updated an env dir change in the changelog and got these mixed up 👀 I agree with you, this should be documented in the Changelog and in the hmr.port config. Let’s talk in #7545 and do it once it is clear that this is what is expected

来自#7545的解决方法。这是一个无证的重大变化还是一个意外的回归？

导出 默认 defineConfig （{
  服务器：{ 
    hmr：{  clientPort：443  } ，
    主机：“0.0.0.0” ，
    打开：false ，
    端口：80 ，
    strictPort：true ，
  } ，
} ）；

谢谢谢谢，对我有帮助
