问题
I'm not able to connect RoboMongo with Amazon instance. Tried this http://blog.mongohq.com/robomongo-your-next-shell/
Opened inbound port in the instance. Still no Luck. Anyone have done this?
Edited:

After I press test or connect it goes on and seems it's trying to connect but after a while a message pops up saying unable to connect with mongodb.
Edit
by setting the host as 'localhost' worked.

From @Stennie
"Have you tried connecting via ssh with the same credentials? On the Robomongo Connection tab, have you set hostname to "localhost"? I would try logging in with ssh, then use the same details as the Connection tab to make sure this connects, eg: mongo localhost:27017."
