Hi i faced exactly same issue. and you should see error in heat-api.log as below:
```
2017-08-25 14:24:48.962 2778 WARNING keystonemiddleware.auth_token [-] Identity response: {"error": {"message": "The request you have made requires authentication.", "code": 401, "title": "Unauthorized"}}
```
the issue is credential you configured in heat.conf for keystone_token.

are you sure your passowrd for user heat is as the one your configured?
```
password = HEATPASS
```
