I just tested that code-insiders works on WSL 2.0.4.

Anything special in the WSL log?

Maybe restart WSL with wsl --shutdown?

[pocesar]

Ah, it's the networkingMode=mirrored + dnsTunneling=true that does this

[Berrysoft]

Is there any way to make vscode remote work with mirrored networking?

I tested mirrored mode yesterday and it seemed to work. If you have any additional details, please comment in microsoft/vscode-remote-release#9222
