Does this issue occur when all extensions are disabled?: Yes/No

Issue similar to #190859 - this time it affects Devcontainers running on remote ssh hosts ⚠️

Client: Windows 11 Remote-Host: Ubuntu 22.04 Container: Debian 11 Repo for reproduction: https://github.com/gecio/gecio.github.io

Steps to Reproduce:

Connect to ssh host
Clone Repo
Open in devcontainer when asked
Launch Task “Serve” to start webserver
Open http://localhost:4000 and see indefinite loading.

I can’t test it without the remote ssh host 😕

Dev console doesn’t contain anything related.

The extension host shows:

Although I’m not sure if that’s related.

The server output is interesting:

2023-08-31 23:03:58.609 [error] Error: connect ECONNREFUSED ::1:4000
    at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1494:16)

This is directly related - it happens right/shortly after opening the url in the browser.

The code that sets up a tunnel executes in the server process, where it tries to connect to localhost, so that is why the extension host flag doesn’t have any effect. I also like the idea of using node’s builtin autoSelectFamily rather than us reimplementing it.
