VS Code Copilot extension can't reach server on WSL Remotes

[selfagency]

Type: Bug

Copilot today stopped working in VS Code on WSL Remotes. It works fine when I'm using a local repo within Windows. But if I remote into WSL, it tells me to "Sign in to GitHub.com" and then nothing happens when I click "Sign in." This is effecting both the Chat and standard plugins in both the latest general and preview releases. I can verify that I am able to reach github.com from within the VS Code terminal on WSL.

I was also just able to login to the Codespaces plugin from within WSL without issue.

I turned on a web proxy service and routed WSL through it and it worked. But without the proxy, it doesn't.
