I am following the installation guide https://hortonworks.com/tutorial/sandbox-deployment-and-install-guide/section/4/

I am able to see Splash screen. Registration was successful. there are some issues here.

1) when I click on Launch Dashboard in "New to HDP", I get an error message. "Safari can't open the page "localhost:8080/#/main/dashboard/metrics" because the server unexpectedly dropped the connection.. " I tried so many times but it was never successful. I've attached the screenshot.

2) When I click on "Click Links" on "Advanced HDP", it opens up the page nicely. However, among the 6 links, I can access only Zeppelin http://localhost:9995 and SSH built-in web client http://localhost:4200. Others all fail. AMBARI http://localhost:8080, ATLAS http://localhost:21000, FALCON http://localhost:15000, RANGER http://localhost:6080 all error out. The error messages are identical to 1). "Safari can't open the page "localhost:port number" because the server unexpectedly dropped the connection...." Please see attached.

my SSH config files contain all of them.

I tried it in different browser (FireFox as well as Safari), in different networks (work and home) but no luck. I have no idea what could be wrong. Could you please advise?

try to connect via SSH to port 2222 instead of 22. As far as I know the sandbox is build by a basic RedHat image, and all Hortonworks is installed via Docker. This results in the effect that if you use Port 22, no Hadoop components seem to be installed.
