Unable to login to built-in web client at port 4200 using HDP 2.5 set-up in Microsoft Azure.

[#1]

I had setup a HDP 2.5 sandbox in microsoft azure. I am able to login the VM successfully through putty and access all the hadoop services but am unable to login to SSH client from web-client using "http://<my-ip-address>:4200". I even opened the port 4200 from azure. still am facing the error :

Network Error (tcp_error)

A communication error occurred: "Connection refused"

The Web Server may be down, too busy, or experiencing other problems preventing it from responding to requests. You may wish to try again at a later time. Please help...

4200 web terminal port is opened by the service "shellinabox".

So can you please check if that service is running or not?

- I do not have Azur VM ready at my end currently to check the same. However in HDP sandbox for Linux i see that this service is up as following:

# shellinaboxd -u shellinabox -g shellinabox --cert=/var/lib/shellinabox --port=4200 --background=/var/run/shellinaboxd.pid -t -s /:SSH:sandbox.hortonworks.com --css white-on-black.css
