Deployment with subscription failed with timeout error

We have a blueprint to create VM on vSphere with a subscription to complete configuration on state "VMPSMasterWorkflow32.MachineProvisioned" phase PRE on vRA 7.6

We configured :

• Timeout to 20160 minutes (14 days) on workflow subscription
• Add this setting <addkey="Extensibility.VMPSMasterWorkflow32.MachineProvisioned.PRE.Timeout"value="14.00:00:00.0"/> in C:\Program Files (x86)\VMware\vCAC\Server\ManagerService.exe.config on Manager Service Service

A user request this blueprint. 72 hours after, the deployment fail with error "The following component requests failed: VMWindowsServer. Component Request [b70ff5e8-7b09-4676-8d02-e2523698cb71] terminated due to timeout". The workflow are still in waiting of a user interaction.

What's wrong

Thanks
