We are continuing to investigate an issue impacting Zscaler Client Connector sign-in/registration and access to the Mobile Admin Portal for a subset of users on ZS2. Initial mitigation actions did not fully restore service. We identified a contributing configuration change that reduced service capacity for the Mobile Admin Portal on ZS2, which led to intermittent access issues for some users. Our teams are reverting the change and actively applying additional remediation steps to recover affected services. We are monitoring recovery and will provide further updates as more information becomes available.

Update - Mon, 20 Jul 2026 16:35:29 UTC

We have reverted the contributing configuration change and implemented additional adjustments to improve service capacity on ZS2. We are currently validating these changes and monitoring recovery for Zscaler Client Connector sign-in/registration and Mobile Admin Portal access. We will provide another update as validation completes or if service status changes.
