Getting IAM license

Hi, 

I am trying to get the API Manager up and running. 

I have enabled the application and IAM user and changed password.

when we run the iam_setup.sh I get the following.

Getting IAM license using your inputs...
Internal server error when testing inputs

I have check on Iris management portal , but could see no errors.

On the cspgateway I see

HTTP/1.1 500 Internal Server Error
Content-Type: application/json; charset=utf-8
Cache-Control: no-cache

"errors":[ {

"domain":"%ObjectErrors",
"error":"ERROR #6220: Internal Server Error",
"id":"InternalError"
}
],
"summary":"ERROR #6220: Internal Server Error"
}{}


Any idea what I can try to resolve the issue?
