- Claude Code on Windows fails to log in with the error "OAuth error: timeout of 15000ms exceeded," completely preventing the reporter from using the application.
- The bug was filed as issue #44257 on the Claude Code GitHub repository, with the user reporting the issue on Claude Code version 2.1.92 running on Windows with WSL (Windows Subsystem for Linux).
- The reporter attempted login multiple times using their Google account and encountered the identical 15-second timeout on every attempt, even after successfully completing the browser-based sign-in flow.
- The user noted that version 2.1.92 was also listed as the "last working version," leaving it unclear whether the issue is a regression or a persistent flaw.
- Anthropic's API platform was specified as the affected platform in the bug report metadata, and the issue was labeled a confirmed bug.
Why it matters: A hard login blocker that fires after just 15 seconds is unusually aggressive for an OAuth flow, and the fact that it occurs after the browser sign-in completes suggests the client-side callback handler is the failure point — not Google's auth service. For Windows users relying on Claude Code as a daily driver, a complete sign-in outage means zero access until a fix ships.
