Had a simalar options with 4.1.0-rc.7, seems no this issue.
The steps are:
1.Get openshift-install binary file with cmd:
oc adm release extract ---command='openshift-install' --command-os='linux' quay.io/openshift-release-dev/ocp-release:4.1.0-rc.7
2. Install an openshift cluster in ap-northeast-1 region
3. Wait about 1 or 2 hours
4. Stop all the instances in the aws web console
5. Then start all the instances in the aws web console
6. Check the cluster with cmd: oc get node, and succeeded
