I have Robo 3T-1.3 installed on my ubuntu 16.4 LTS. It is showing me the following error:
`Cannot connect to the MongoDB at localhost:27017.
Error: Network is unreachable. Reason: couldn't connect to server localhost:27017, connection attempt failed: SocketException: Error connecting to localhost:27017 (127.0.0.1:27017) :: caused by :: Connection refused`
How to solve it?
