### Cause <a href="#cause" id="cause"></a>

This issue is due to Spinnaker not caching ECS subnets and server groups in the cluster. There were naming issues within Clouddriver and Deck pertaining to servergroups and subnets:<https://github.com/spinnaker/deck/pull/9524><https://github.com/spinnaker/deck/pull/9032>
