Steps to Reproduce:

1. Login to VS Code Remote Linux Environment
2. In the Copilot chat window click on Sign in to GitHub Copilot.
3. The browser tries to open a URL like **http://127.0.0.1:49349/**signin?nonce=v842QbeQcijwk4uybpuIiw==
4. Stuck there for ever.
5. If we cancel the login from VS Code and try using "You have not yet finished authorizing this extension to use GitHub. Would you like to try a different way? (url handler)", the login works.

I don't have any GHE related settings in my VS Code. All the Copilot and GitHub URLs are accessible from my remote server via outbound proxy. It is not just me, almost all from my company face this issue.

Can you run this command in the command palette? (cmd+shift+p):

>Developer: Show Running Extensions

And send me a screenshot of what you see in the GitHub Authentication row?

Hi Tyler,

Please find the screenshot below. At the bottom right, you can see the authentication is stuck. In the browser it has opened a URL like "http://127.0.0.1:49349/**signin?nonce="

@chrmarti @alexr00 this is verrrry odd. I've gotten a few reports of this over the past couple weeks that all have to do with remote environments.

The extension is obviously running on the UI side and it opens a port there for the user to load in their browser...but since it's a UI extension the fact that it's a remote shouldn't matter.

Any ideas? One user mentioned that they had to change the port in their browser and then it worked.

Hey, I'm facing the same issue. What did they change their port to for it to start working?
