The best way to debug this is probably to look for the responsible error in the Cloudformation event log for the cluster. It should tell you the cause of the problem, and whether it is that the region is overloaded or id it is a permissions/IAM related problem.
You can also add --verbose 5
to the eksctl command to see better output in the console.
If it is permissions related and not a region capacity error, make sure the AWS user/profile that you are using has at least the following permissions:
