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?
Firstly check your mongo status via this command.
sudo systemctl status mongod
OR
You can follow this link.

I'm using homebrew to initialize mongodb as it follows:
brew services start mongodb-community#5.0
It starts successfully
==> Successfully started mongodb-community (label: homebrew.mxcl.mongodb-community)
However, when I type mongoto run mongodb, I keep getting connection refused:
MongoDB shell version v5.0.2
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed: SocketException: Error connecting to 127.0.0.1:27017 :: caused by :: Connection refused :

#(connect):2:6
exception: connect failed
exiting with code 1
So I typed brew services list to check if the mongoDB is up, and it seems it started with an error status:

check the following.
if you are using M1 based MacOS then install mongo db (and brew) with Rosetta.
check the IP binding on mongo config
(/usr/local/etc/mongod.conf or /opt/homebrew/etc/mongod.conf)
verify the connection string URI format - Mongo docs - connection-string-uri-format

I had the same problem. Try starting the mongo shell with:
mongod --dbpath /usr/local/var/mongodb --logpath /usr/local/var/log/mongodb/mongo.log
Details are in the mongoDB docs:
https://docs.mongodb.com/manual/tutorial/install-mongodb-on-os-x-tarball/
I am running a mean app, but when I go to run 'mongo', I get the following error:
MongoDB shell version v4.0.0

I am sure I am missing something simple here.
mongo is the Mongo shell. It connects to the Mongo daemon, mongod, which isn't running - hence the error.
At the command-line: sudo mongod
Enter your password, and the daemon should start. Now, when you run mongo it should start up ok.
I have facing issues while running mongo commend after successful installation of mongoDB version 3.6.3.
I have run mongo commend and got the following error

Run into the same problem, my error was that I was this command:
sudo mongo service mongod start
Instead of this:
sudo service mongod start
Make sure you run the second one, hopefully that is your error source as well.
