Anthropic's Claude Code Hits Critical Login Bug on Windows, Locking Users Out for Hours
Key Takeaways
- ▸Claude Code login fails on Windows with consistent OAuth timeout errors (15000ms), completely blocking user access
- ▸The bug occurs after users successfully complete the Google sign-in flow in their browser, suggesting a communication issue between the browser and desktop app
- ▸Multiple login attempts and retries do not resolve the issue, indicating a systematic problem rather than a transient error
Summary
Anthropic's Claude Code application is experiencing a critical authentication failure on Windows systems, preventing users from accessing the tool entirely. The bug manifests as an OAuth timeout error (15000ms exceeded) during Google account login, occurring consistently across multiple login attempts. Users report being completely blocked from using Claude Code, with the authentication process failing at the final step after successfully completing the browser sign-in flow.
The issue appears to be a regression in the OAuth implementation specific to Windows environments, with users unable to work around the problem through retries. This represents a significant service disruption for Windows-based developers who rely on Claude Code for their workflow, as the timeout prevents the authentication token from being properly relayed back to the desktop application.
- The bug appears to be Windows-specific, with no reports of similar failures on other operating systems
