Foundry deployment: Failure at project scope with context deadline exceeded — Permission and subnet delegation issues

Hi @em_maz_cl_t_o

To better understand the deployment failure and investigate the reported context deadline exceeded, permission, and subnet delegation issues, could you please provide the following details?

1. What exact deployment type are you doing when it fails?
   • Foundry Prompt Flow, model deployment, or Agent Service / capability host?
2. Can you paste the full error text and any ARM response details around the failure (especially the “permission” and “subnet delegation” parts)?
3. Are you using private networking for Foundry (and delegated subnets), or is this public networking?
4. For subnet issues: what is the subnet delegation configured to, and what CIDR range are you using?
5. Which identity is performing the deployment (user vs managed identity), and do you know whether it has:
   • Contributor on the Foundry account
   • User Access Administrator or Owner for dependent resources?
6. Does the account-level capability host exist already (if this is Agent Service-related), before creating the project-level one?

Thank you!

Following up on our previous response, could you please share the requested deployment details and the full error message, including any ARM response details related to the context deadline exceeded, permission, and subnet delegation errors?

Thank you!
