Cloudbreak cluster in "update in progress" status doesn't sync

[#1]

I have a running cluster in AWS that appears as update in progress:

cb cluster list
{
    "Name": "hdp-edw-v21",
    "Description": "",
    "CloudPlatform": "AWS",
    "StackStatus": "UPDATE_IN_PROGRESS",
    "ClusterStatus": "START_IN_PROGRESS"
 }
the cluster is running, and I can see all services up and running in ambari.

If I try to sync using web ui or console cli, the cluster keeps in this status.
Right now I cant stop or resize the cluster using cloudbreak.

How can I fix this? 
Thanks in advance

After digging cloudbreak logs I realized it wasn't able to connect to cluster master. After reviewing security groups, there were some ports closed (9443) in master instance group.

Once I set them correctly, the cluster succesfully syncronized
