    The Horizon Cloud Service team is investigating reports of issues with Custom Client Access Subdomain URLs (.omnissahorizon.com). Users accessing this URL may experience Desktop/Application launch failures. Existing user connections remain unaffected. As a workaround, we recommend using the https://cloud.omnissahorizon.com URL to launch Desktops. We are looking into this further and will provide more information soon. Service reliability is a top priority at Horizon Cloud Service, and we are continuously improving our systems.
