Errors
browser_auth_disabled
Browser authentication is not configured for this deployment.
browser_auth_disabled is a 503 returned by the browser sign-in routes when the deployment has no browser authentication configured. It is a deployment state, not a rejection of your credentials — nothing about the request or the account caused it.
Recovery guidance
There is no client-side retry that resolves this. API-key access is unaffected, so machine integrations can continue while browser sign-in is unavailable. If you see this on a deployment that is supposed to support browser sign-in, preserve requestId and report it — the fix is in the deployment's configuration.
