Claude Code errors / Auth
OAuth error: timeout of 15000ms exceeded
Cause
DNS resolution for auth.anthropic.com fails in certain regions/networks, so the OAuth login request times out after 15 seconds.
Fix
Confirm auth.anthropic.com resolves with 'nslookup auth.anthropic.com 8.8.8.8'. If not, use a VPN or a different DNS server. Alternatively authenticate via API key by setting ANTHROPIC_API_KEY instead of the browser OAuth flow.
