Cloud PC users may encounter connection failure when they restarted the Cloud PC after Windows update or suddenly lose connection without obvious reason. These blog troubleshooting steps are not for a special reason of connection failure. It is a general troubleshooting method for users themselves and Cloud PC admins to bring the Cloud PC back online.
If users restarted Cloud PC because of Windows feature update, it is reasonable to wait around 30 minutes to get a connection because Cloud PC backend infrastructure needs more time to resume all services for supporting Cloud PC than a regular physical devices restart.
