Issue Type
Bug
Description
I am unable to sign in to access the Extensions Marketplace.
The GitHub authentication flow starts normally. My browser opens and I can reach the "Authorize Visual Studio Code" page. After selecting my GitHub account and authorizing Visual Studio Code, the browser redirects back to VS Code, but authentication never completes successfully.
VS Code reports that authorization is incomplete and eventually displays:
No auth flow succeeded
As a result:
- Marketplace remains locked.
- Extensions cannot be searched or installed.
- GitHub Copilot commands are unavailable.
- Authentication repeatedly loops.
Steps to Reproduce
- Open VS Code.
- Open the Extensions view.
- Click "Sign in to access Marketplace".
- Browser opens GitHub authentication.
- Select GitHub account and click "Authorize Visual Studio Code".
- Browser redirects back to VS Code.
- Authentication does not complete and eventually reports "No auth flow succeeded".
Expected Result
Authentication completes successfully and Marketplace access is granted.
Actual Result
Authentication fails with "No auth flow succeeded" and Marketplace remains inaccessible.
Attempted Fixes
- Reinstalled VS Code.
- Deleted
%APPDATA%\Code\User\globalStorage. - Reloaded the window.
- Used Chrome as the browser.
- Repeated authorization multiple times.
- Browser login succeeds, but VS Code does not appear to process the callback successfully.
Additional Notes
The issue is consistently reproducible. The browser authentication itself succeeds, but the callback to VS Code appears to fail, preventing Marketplace access and extension installation.
