I'm hitting this issue, my reproduction steps are running LXC container with ipv6-only setup through SLAAC and connecting to it using ms-vscode remote, then install dart+flutter extensions and use ms-vscode to open a flutter project.

Can you take a look at this @derekxu16?

when running a simple app with 'flutter run -d web-server' and getting to http://127.0.0.1:9100 in chrome,devtools also shows the dart tooling daemon error, ms-vscode does 127.0.0.1 redirections automatically which works for the web app in some random port but web-tools fails to connect to it with the second websocket error when I click 'connect' (PS: part of the problem seems flutter-specific but the originating issue got closed in favor of this one so in the future it may require a new one).

@bkonyi Can we reassign this or lower to P3?

[bkonyi]

Yes, let's reassign this.
