Service Limits Exceeded
OS Management Hub has limits on the number of resources per region.
When you try to create a resource, you might see the following error:
The following service limits were exceeded: <resource-count>. Request a service limit increase from the service limits page in the console.
This issue most commonly occurs when trying to use OS Management Hub on Free Tier, which isn't supported. Upgrade your account to use OS Management Hub.
See Service Limits to review the limits for OS Management Hub resources. If you need to increase the limits, you can request a service limit increase.
