The SendFailure is important. It means the cmdlet cannot complete its HTTPS request to the clustered Azure Stack HCI Update Service on port 4900; the NullReferenceException is usually a follow-on because no response object was returned. Since the GatewayTimeout procedure did not help, run Get-ActionPlanInstances and confirm it responds quickly. If it stalls, move the Azure Stack HCI Orchestrator Service Cluster Group. Next confirm the Azure Stack HCI Update Service Cluster Group is Online, note its owner node, and test DNS resolution and TCP 4900 to the reported FQDN from every node. On the owner, review the Application log for AzureStack Agent Lifecycle Agent events, especially Update Service termination or memory-limit errors. Move the Update Service cluster group once and retest. If the endpoint still fails, collect diagnostic logs and open Microsoft support with UTC timestamps; 2604 release notes do not list this exact error as a known issue.
