Symptoms

The error might be reported during daily or weekly admin.

Cause

1. The rolling upgrade feature is enabled on DS-System side and the DS-Client reporting the errors does not have a time interval set for allowing the auto-upgrade or the interval does not include current time (so auto-upgrade is disabled).
2. The DS-User auto-upgrade packages are missing from DS-System online storage, Upgrade folder.

Workaround

1. Enable back the rolling upgrade for the DS-Client that was already upgraded.
2. Ensure the DS-User auto-upgrade packages are available on DS-System side.
