Hello,

I am experiencing a persistent API connection issue where the Gemini Agent in VS Code is unstable.

Core Problem:
The "Agent is working" status never appears. After one successful prompt, all subsequent prompts fail with the error: [API Error: An unknown error occurred.]

Key Finding:
This error happens consistently, even in a completely empty folder. The problem is not related to project size or complexity.

Exhaustive Troubleshooting Steps Performed:

• I have performed a complete clean reinstall of VS Code, including manually deleting the user data folders (%APPDATA%\Code and %USERPROFILE%\.vscode).
• I have created a brand new, clean Google Cloud project where I am the full "Owner".
• The new project is linked to a new, active Billing Account.
• "Gemini API" and "Cloud AI Companion API" are both enabled in the new project.
• I have bypassed my local Mikrotik router and connected my PC directly to my ISP's modem, and the issue still persists.

Conclusion:
The issue does not appear to be related to my local configuration, project setup, or local network hardware. The problem seems to be a fundamental connection/authentication bug, possibly related to my account or network routing from my region (Indonesia) to the nearest available servers (likely Singapore).

Thank you for your assistance.
