An Azure service that enables the connection of on-premises networks to Azure through site-to-site virtual private networks.
Hi ChrisGraham-2510 & thx for join me at Q&A platform,
If the gateway is showing Standby because of a platform upgrade and you also can't delete, reset, or modify it, this is no longer a normal VPN connection/configuration issue. It points to the VPN Gateway resource being stuck in an Azure-managed control-plane operation.
I wouldn't keep trying to delete and recreate it while that operation is active. If Azure still considers an upgrade or maintenance workflow in progress, conflicting management operations can remain blocked, and repeated delete/update requests won't clear the underlying state.
Because production connectivity is already down, this needs to be treated as a service-side outage and escalated to the Azure VPN Gateway / Networking engineering team. Give support the gateway resource ID, region, exact UTC time the outage started, Activity Log correlation IDs, current provisioning/operational state, and the entries showing the gateway entering Standby. Ask them specifically to check for a stuck platform upgrade/maintenance operation and recover or clear the gateway backend state.
If the gateway has remained in Standby for hours with all tunnels down and management operations blocked, there isn't a customer-side configuration change that can reliably recover it. Microsoft needs to inspect the gateway instances and the platform operation holding the resource before deciding whether the existing gateway can be recovered or must be reprovisioned.
rgds,
