Cannot launch cluster

Question

I am trying to launch a cluster using pcluster with default settings (which comes from "pcluster configure") but the cluster creation does not finish successfully.  
  
It always get stuck at MasterServerSubstack, MasterServer creation. It says "CREATE_IN_PROGRESS" for status and "Resource creation Initiated" for status reason. The master node launches successfully and I am able to ssh to it but the status is still "CREATE_IN_PROGRESS". pcluster cannot complete the cluster creation. After a while, it starts to rollback. What do I do wrong?  
  
Can this be because of "cluster_resource_bucket" setting? I did not set it and the documentation says that "If this parameter isn't specified, a new bucket is created when the cluster is created."  
  
Update:  
After several trials, it worked. I do not know why it worked this time.

Hi baran,  
  
Glad to see you solve the problem! If you are still interested in this question, could you share your configuration and logs so we can try to find the root cause?  
If the cluster fails creation, please re-execute `create` action using `--norollback` option and attach `/var/log/cfn-init.log`, `/var/log/cloud-init.log` and `/var/log/cloud-init-output.log` files from the Head node
