Claude Code authenticates to Console instead of claude.ai Max subscription on Windows (winget install) — ConnectionRefused error

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

OS: Windows 11
Versão: 2.1.137 (winget)
Problema: OAuth redireciona para platform.claude.com mesmo com --claudeai
Assinatura: claude.ai Max ativa

What Should Happen?

claude auth login --claudeai should authenticate against the claude.ai Max subscription, not the Anthropic Console. All API calls should succeed without requiring Console balance.

Error Messages/Logs

API Error: Unable to connect to API (ConnectionRefused)
Retrying in Xs · attempt N/10

Steps to Reproduce

1. Install Claude Code via winget: winget install Anthropic.ClaudeCode
2. Run: claude auth login --claudeai
3. Observe OAuth URL in terminal — redirect_uri points to platform.claude.com/oauth/callback instead of claude.ai
4. Complete browser authentication (Login successful)
5. Run any command in Claude Code
6. Error: Unable to connect to API (ConnectionRefused)
7. Claude Code welcome screen shows "API Usage Billing" instead of claude.ai subscription
