Scheduled
Horizon Cloud Service Next-Gen will perform scheduled maintenance on the APAC VM Hub during the window listed below.
This update will remove support for the Legacy Certificate Authority, as outlined in the previously communicated KB article: https://kb.omnissa.com/s/article/6000824
Maintenance Window: • Start: Sunday, August 31, 2025 – 12:30 UTC • End: Sunday, August 31, 2025 – 20:30 UTC
Impact: • Virtual Machines (VMs) which couldn’t be updated to new Omnissa Certificate Authority, will lose connectivity to the Horizon Cloud next-gen control plane after this update. This means: • Users won’t be able to access the affected Virtual Machines (VMs) and applications. • The VMs will show as "Unavailable" in the Horizon Universal Console. • For instructions on how to recover and repair these affected VMs, please refer to following KB article: Repairing and Recovering Single-session and Multi-session Pool VMs That Lose Connectivity to Horizon Cloud Next-Gen after Root CA Update (6000944) (https://kb.omnissa.com/s/article/6000944). • VMs which were already rotated to new Omnissa Certificate Authority, are generally unaffected except Next-Gen desktop or application users may experience intermittent access issues. However, retry should succeed.
