Ho trovato questo, che include alcune risposte che fanno riferimento a Discourse:

> <https://github.com/microsoft/vscode-remote-release/issues/9969>
>
> Type: \<b\>Bug\</b\>
> 
> VSCode 1.91.0-insider (reproducible with latest stable relea…se)
> Docker version 25.0.3, build 4debf41 (installed within WSL, not docker desktop)
> 
> Run local devcontainer within WSL (ubuntu 22.04 image)
> Run any http webserver and port forward with vscode to windows host (I have best luck reproducing with flask python server)
> Access content from windows host browser.
> This seems to depend on the size of the content, most reliable when it is at least \>100kb
> 
> Expected Behavior
> Content is successfully displayed in the browser
> 
> Actual Behavior
> Content appears to be truncated, browser logs
> Failed to load resource: net::ERR\_CONTENT\_LENGTH\_MISMATCH
> 
> It is worth noting that this issue does NOT happen when running and port forwarding the application in WSL directly, ONLY when running in a devcontainer
> 
> Extension version: 0.372.0

Sembra che sia stato risolto tramite [Prevent truncated responses through managed port-forwarding sockets - Pull Request #338875 - microsoft/vscode - GitHub](https://github.com/microsoft/vscode/pull/338875), che è stato unito qualche giorno fa. Dovrebbe già essere disponibile nella build ‘insiders’ di VSCode 🤞
