Incident Timeline
Resolved
Zscaler has resolved the issue preventing a subset of administrators from logging into the Zscaler Admin Console. The issue was caused by a routing defect introduced in a recent build upgrade that caused IDP-based authentication requests to be misrouted to an incorrect region, resulting in a tenant lookup failure and 401 unauthorized error. The build has been successfully rolled back to the previous stable version, and admin console login has been confirmed restored.
