Root cause
A corporate proxy with a self-signed/MITM certificate breaks TLS verification, so the CLI can't reach the auth or API endpoints.
How to reproduce
Run `claude login` behind a corporate proxy that injects its own CA; the request fails on cert verification.

#1Applies to 1.0.x
Point Node/CLI at your corporate CA bundle: set `NODE_EXTRA_CA_CERTS=/path/to/corp-ca.pem` so TLS verification passes through the proxy.

Set HTTPS_PROXY to your proxy URL and confirm the auth/API domains are allowlisted by your network team.
