Description

GitHub Copilot Chat is not responding when sending prompts. After selecting any model and submitting a question, nothing happens in the chat interface.

Authentication appears to succeed, but the extension fails to retrieve the Copilot token due to repeated connection timeouts.

Steps to Reproduce

1. Open VS Code.
2. Sign in to GitHub Copilot.
3. Open Copilot Chat.
4. Select any available model.
5. Send a prompt in Ask mode.
6. Observe that no response is generated.

Expected Behavior

The selected model should process the prompt and return a response.

Actual Behavior

No response is returned in the chat. Logs show repeated timeout errors while attempting to retrieve the Copilot token.

Additional Context

• Location: Brazil
• Authentication succeeds (Logged in as hugo-autotrac)
• The issue occurs regardless of the selected model.
• Multiple timeout errors occur while connecting to Copilot services.
• The logs repeatedly reference 4.228.31.149:443.
• This may indicate a regional networking, routing, CDN, or service availability issue affecting Copilot users in Brazil.
