Prefect Community

Hey all, I am new to Prefect (Cloud) and am trying to set up flow runs on an ECS cluster with Fargate using <https://docs.prefect.io/latest/guides/deployment/push-work-pools/|serverless push work pools>.
My task runs are _sometimes_ failing with
```CannotPullContainerError: pull image manifest has been retried 5 time(s): failed to resolve ref <http://docker.io/prefecthq/prefect:2-latest|docker.io/prefecthq/prefect:2-latest>: failed to do request: Head "<https://registry-1.docker.io/v2/prefecthq/prefect/manifests/2-latest>": dial tcp 34.205.13.154:443: i/o timeout```
I assume this is a connectivity issue and due to the ECS tasks being deployed in a _random_ subnet, and if it is `private` the error occurs (no NAT gateway).
How do I specify a subnet for my tasks? I couldn't find it in the Base Job Template of my work pool, is that even the right place?
Much appreciated if someone could point me in the right direction.
