Hi Chris, I had some success. I used the IP address given by my Virtual Box manager to get the Splash page using port 1080. Previously, I had reset the Ambari password using Geoffrey's instructions above, using port 4200. Then I was able to open Ambari and login with my new password from the Splash page , I got to the Splash page by: 192.168.0.26:1080 Having reset the Ambari password as shown by Geoffrey above, I was able to open Ambari with admin/new password. I got to Sandbox-hdp login by: 192.168.0.26:4200 Hope this helps.
