The proxy rejected the login session with HTTP {response.sta

Error message

The proxy rejected the login session with HTTP {response.status_code}

What it means

The CLI SSO poll loop received a non-200 from the polling endpoint, meaning the login session was rejected server-side (expired, revoked, or mismatched). Surfaced as ValueError to abort the login flow.
