Managed Devops Pool stuck at Provisioning State

Hi all,

I already have an open support ticket, but not much progress is made in the last days - so maybe someone has a good idea or hint.

We want to provision a managed devops pool and inject it into a vnet.

However, the deployment is just "stuck" at the provisioning phase, meaning it runs for 30mins, 60mins, what ever and then fails without any meaningful error details.

The support confirmed permissions on the devops (must be member of Project Collection Administrator) increased quotes etc. I already tried different european regions and skus to no avail.

For the vnet injection I verified that DevopsInfrastructure has the necessary permissions and that the subnet delegation is added.

However, I also tried to deploy with an isolated network which behaves the same unfortunately.

Errormessage I get:

{   "message": "The request has been completed with result Canceled. Please check details with more information.",   "details": [],   "additionalInfo": [] }
