Ambari URL working, but not the URL to initiate my Hortonworks Sandbox session not working

[#1]

http://127.0.0.1:8080 prompts me for login credentials for Ambari. I can successfully log in with username: admin, password:admin.

I get the following error when using: http://127.0.0.1:8888

Not Found

---

HTTP Error 404. The requested resource is not found.

I am using Chrome Version 48.0.2564.97

Thanks in advance for any help.
