Zscaler Client Connector for Virtual Desktop Infrastructure (VDI) Deployment Issue

Zscaler detected an issue where the existing access token that was generated before April 11, 2026 can not be used to deploy Zscaler Client Connector for VDI. As a workaround customers can create a new access token while the Zscaler team investigates and fixes the issue. We will continue to provide updates here as the investigation progresses. Status changes and additional details will be posted there as they become available.Customer Impact: Customers won’t be able to deploy Zscaler Client Connector for VDI using existing access tokens that were created before April 11 (administrators generate access tokens in the Cloud and Branch Connector portal under Administration > VDI Templates). Administrators will receive "Init Config error" once they try to deploy Zscaler Client Connector for VDI with an existing access token.Customers running non-persistent VDI deployments and do not have a backup restore mechanism implemented to restore user profiles and config files stored in %programdata%/ZCCVDI. In this case, the agent must re-enroll on every boot using the access token from the golden image. If the golden image contains an access token generated before April 11, every boot will fail with "Init Config error" until the golden image is updated with a new token. Already-enrolled agents in persistent environments are not affected, as they do not need to re-enroll.Workaround: Generate a new access token from the Cloud and Branch Connector portal (Administration > VDI Templates) and use the new token for any new deploymentsFor non-persistent VDI where no user backup/restore  was implemented: Update the golden/master image with the new access token, this is critical since the agent re-enrolls on every boot.
